4.3 Determining Equivalent Units When units of work-in-process (WIP) inventory exist at the end of the reporting period, process costing requires that these partially completed units be converted to the equivalent completed units (called equivalent units).The equation used to calculate equivalent completed units is as follows:hen units of work-in-process (WIP) inventory exist at the end of the reporting period, process costing requires that these partially completed units be converted to the equivalent completed units (called equivalent units).

- Mechanical energy and work are the same thing. Work is the force  times the distance moved in the direction of the force. So lifting  a 1 kg mass by 1 metre represents an am…ount of work equal to the  weight times the distance: 9.806 Newtons times 1 metre equals 9.806  Joules.

Work and energy work done by gravity = W = mgh (h = height lost by the object). An alternate way of looking at this is to call this the gravitational potential energy. An object with potential energy has the potential to do work.

Definition and Mathematics of Work In fact, any unit of force times any unit of displacement is equivalent to a unit of work. Some nonstandard units for work are shown below. Notice that when analyzed, each set of units is equivalent to a force unit times a displacement unit. Non-standard Units of Work:

What term represents the rate at which work is done? Work is done on an object by a force if the object moves in the direction of the force. Work done is defined as the integral of the force acting over the distance travelled du…e to that force and is the energy change of the object due to that force.

Energy, heat, and temperature 1 Joule is the amount of work done when a force of 1 Newton moves any point mass by a distance of 1m. For a unit of Joule to be used for a unit of Torque, you would need a unit of Torque to always perform 1 Joule of work, which is not true.

- W = p * V We can do a quick units check to see that pressure force / area times volume area * length gives units of force times length which are the units of work W = (force / area) * (area * length) = force * length In the metric system the unit of work is the Joule, in the English system the unit is the foot-pound.In general, during a change of state both the volume and the pressure change. So it is more correct to define the work as the integrated, or summed variable pressure times the change of volume from State 1 to State 2. = p * V We can do a quick units check to see that pressure force / area times volume area * length gives units of force times length which are the units of work W = (force / area) * (area * length) = force * length In the metric system the unit of work is the Joule, in the English system the unit is the foot-pound.

Calculating the Amount of Work Done by Forces Calculate the work done by a 2.0-N force (directed at a 30° angle to the vertical) to move a 500 gram box a horizontal distance of 400 cm across a rough floor at a constant speed of 0.5 m/s. (HINT: Be cautious with the units.)

- Define work. Work is easy to calculate. Just multiply the amount of force used, and the amount of distance traveled. Usually, scientists measure force in Newtons, and distance in meters. If you use these units, your answer will be work in units of Joules. Whenever you read a word problem about work, stop and think where the force is being applied.

Work, Energy and Power The amount of work done to push a 10,000 N car a distance of 10 meters would be 10,000 N x 10 m = 100,000 N m or 100,000 J The Newton-meters are termed joules (J).

Energy The SI unit for both energy and work is the joule (J), named in honour of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton-meter and, in terms of SI base units:

Joules in the base units of meters, kilograms and seconds? Report Abuse. The answer is kg (m^2/s^2) work is force times distance. Force is mass times acceleration. w=fd=mad (mass*acceleration*distance) the units are kg*m/s^2*m. You should get the answer above.

- work done = ½mgq x Lq = ½mgLq 2. This is of course equivalent to the earlier derivation. It’s a good idea to sketch the potential energy as a function of q , and picture this as a valley the pendulum slides backwards and forwards in, trading potential energy for kinetic energy and then vice versa.

The Meaning of Horsepower and Torque So, one full rotation around an axis at a radius of one foot with one foot of resistance yields the following amount of work: work = (2 * pi) * 1 lb-ft = 6.2832 lb-ft. Where Torque and Horsepower Converge. As you can see above, horsepower is a measure of work/time, where torque is a measure of work.

power The unit of power in the metric system is the wattwatt. [for James Watt], abbr. W, unit of power, or work done per unit time, equal to 1 joule per second. It is used as a measure of electrical and mechanical power. One watt is the amount of power that is delivered to a component of an electric circuit when a current of 1 ampere. .....

How to Figure Out Direct Labor Cost Per Unit Calculate Per Unit Cost. The direct labor standard rate is your direct labor cost per unit. To calculate the number, multiply the direct labor hourly rate by the number of direct labor hours required to complete one unit.irect labor hours, also known as the direct labor efficiency standard, is the number of direct labor hours it takes to produce one finished item. If you produce goods in batches, you must calculate per unit direct labor hours.

How do you calculate machine efficiency? Machine Efficiency= Work done by a machine on a load divided by work done on a machine by an effort force. multiply that by 100%. Work(J)=force(N)multiplied by Distance(m). The answer above is correct but not much use for a practical situation such as a motor driving a pump or a compressor being driven by a turbine.

How to Calculate Joules For example, suppose you want to calculate the energy of a 700 kilogram (kg) car moving at 20 meters per second (m/s). Plug the values into the kinetic energy equation to calculate the joules, as shown below: Kinetic Energy = 1/2 * 700 kg * 20^2 m/s = 140,000 joules. Calculating Joules of Work. Write the equation for work: Work = force * distance, where work is in joules, force is in newtons, and distance is in meters. Consider the situation for which you would like to calculate the joules of work being done.

Assembly Line Balancing This time is the product of the number of stations and the cycle time at each station. In this example we have 3 stations each with a cycle time of 10 seconds for a total work time of 30 station-seconds. The time needed to make one unit. This is simply the sum of the task times.
