The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
the work a machine does is the work output what it takes to do the work is the work input
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
