Why is the mechanical advantage less than that by the given formula?

The mechanical advantage may be less than that calculated by the formula due to factors such as friction, efficiency losses, or flex in the system. Real-world conditions can impact the actual mechanical advantage achieved in a system.


What is the relationship between the pulley torque and the efficiency of a mechanical system?

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.

How do you calculate the efficiency of an electrical mechanical system?

You could have an electric motor driving a reduction gearbox, for example. The efficiencies of both might be considered individually, or as a whole. As a whole is easier. (Work out/ work in) x 100 = efficiency%. Or, (power out/ power in) x 100 = efficiency%. Or, (force out/ force in) x100 = efficiency%. It depends on what you have to work with, what you use. If you did need to calculate electrical and mechanical efficiencies separately because of different units, the final overall efficiency will be (total of the percentages) / (number of percentages).
