Question

18. A pulley system has a velocity ratio = 5. If the efficiency of the system is 80 %, finds it's
Mechanical Advantage (MA).​

Answer 1

Answer:

THE MECHANICAL ADVANTAGE WILL BE 4

Explanation:

EFFICIENCY = 80%

V.R = 5

SO THE MECHANICAL ADVANTAGE WILL BE = EFFICIENCY *VR

                                                                               = 80/100* 5

                                                                                = 4
