Anyone knw this question??

Answer 1

Answer:

VR= 25, MA= 25 , efficiency = 100%

Explanation:

given :An effort of of 4kgf applied on machine , displacement is 100cm and load is 100kgf moves through distance 4cm

To find :- VR, MA and efficiency of machine

solution:-1. VR( velocity ratio)

= distance through which effort move / distance through which load move do

= 100/4

= 25 answer.

2. MA= load/effort

= 100/4

=. 25

3. Efficiency of machine = MA/VR × 100

= 25/25×100

= 100%
