Question

In a certain weight lifting machine a weight of 1KN is lifted by an effort of 20KN while the weight moves up by 100 mm the point of application of effort moves by 8m find mechanical advantage velocity ratio and efficiency of the machine

Answer 1

Answer:

A simple machine has only one point for the application of effort and one point ... Define Mechanical advantage (MA) , velocity ratio (VR) and ... machine a load of 1400 N is lifted by 50 N effort while the load moves up by ... through a distance of 10 mm. ... Find 1) Max MA,2) Max Efficiency 3) Effort to lift a load of 100 N.
