Question

A horizontal force of 980N is required to slide a sledge weighing 1200kgf over a flat surface calculate the coefficient of friction

Answer 1

Coefficient of friction is 0.08

Answer 2

Given :

fs = 980 N

m = 1200 kgf

μs = ?

________________

fs = μs N

fs = μs × mg

980 = μs × 1200 × 9.8

980/9.8 = μs × 1200

100 = μs × 1200

100/1200 = μs

1/12 = μs

________________

μs = 0.08
