Question

A woman draws water from well using a fixed pulley.The mass of the bucket and the water is 8kg. Force applied by the women is 100 N. Calculate MA, VR and Efficiency.g=10ms^-2

Answer 1

Explanation:

Mass of the bucker with water, m=6kg

Load of bucket and water, W=6×10=60N

Force applies by women, F=70N

Mechanical advantage = Load / Effort =

F

W

=

70

60

=0.86

Hence, mechanical advantage is 0.86
