88.6% efficiency using 3 sig figs
The efficiency of the pulley system is calculated by dividing the output work by the input work and multiplying by 100, so efficiency = (output work/input work) * 100. In this case, the output work is 170 J and the input work is 250 J, so the efficiency is (170/250) * 100 = 68%.
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 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.
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.
A fixed pulley can have any odd number of strands supporting the load.The strand that you pull on doesn't support the load.
The efficiency of the pulley system is calculated by dividing the output work by the input work and multiplying by 100, so efficiency = (output work/input work) * 100. In this case, the output work is 170 J and the input work is 250 J, so the efficiency is (170/250) * 100 = 68%.

That requires a special PULLER to remove the pulley.
That requires the use of a power steering pulley PULLER. ( A special tool ) The pulley is pressed on.
The formula used to calculate mechanical advantage in a pulley system is: Mechanical Advantage Number of supporting ropes or strands.
