In a lifting machine, the effort required to lift loads of 200N and 300N were 50N and 60N respectively. If the velocity ratio of the machine is 20 determine effort loss in friction at 200 N.
(a) 30 N
(b) 35 N
(c) 40 N
(d) 45 N
This question was posed to me during an online interview.
This is a very interesting question from Motion of a Link in portion Velocity in Mechanisms of Machine Kinematics
