The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
The efficiency of a pulley system is typically around 90-95%. This means that 90-95% of the input energy is transferred to the output energy, with the remaining 5-10% being lost to friction and other factors.
The efficiency of the pulley system is 75% if 25% of the energy is lost as heat. This means that 75% of the input energy is used to do useful work, while the remaining 25% is lost as heat.
The relationship between pulley torque and the efficiency of a mechanical system is that higher pulley torque can lead to lower efficiency. This is because higher torque can result in more friction and energy loss in the system, reducing its overall efficiency.
The efficiency of the pulley system can be calculated using the formula: Efficiency = (Work output / Work input) x 100% The work output can be calculated as the weight of the box (175 lb) times the vertical distance lifted (3 m) times the acceleration due to gravity (9.81 m/s^2). The work input can be calculated as the force exerted (440 N) times the vertical distance lifted (3 m). Plug these values into the formula to find the efficiency of the pulley system.
To find the work out, you can use the formula for efficiency: Efficiency = (Work out / Work in) * 100. Given that the efficiency is 95%, you can rearrange the formula to find Work out as follows: Work out = (Efficiency / 100) * Work in. Substituting the values, you get Work out = (0.95) * 95 J = 90.25 J.

(work out/work in) x 100
The efficiency of the pulley system is 75% if 25% of the energy is lost as heat. This means that 75% of the input energy is used to do useful work, while the remaining 25% is lost as heat.
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
The relationship between pulley torque and the efficiency of a mechanical system is that higher pulley torque can lead to lower efficiency. This is because higher torque can result in more friction and energy loss in the system, reducing its overall efficiency.

the frmula for pulley is th weight by its mass
Friction in a pulley system mainly occurs where the rope makes contact with the pulley wheels. This friction results in energy loss, reducing the overall efficiency of the system. Lubricants or ball bearings can help minimize this friction and improve efficiency.
The formula to calculate the mechanical advantage of a pulley system is MA 2 number of movable pulleys.
