Question

A tool chest has 720N weight that acts through the midpoint of the chest. The chest is supported by feet at A and rollers at B. Please answer.

Do not round intermediate calculations, however for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to three significant figures. A tool chest has 720 N weight that acts through the midpoint of the chest. The chest is supported by feet at A and rollers at B . The surface has a coefficient of friction of 0.327. Determine the value of the horizontal force P necessary to cause motion of the chest to the right, and determine if the motion is sliding or tipping. P = N and the motion is

Explanation / Answer

let reaction at rollor is R1 vertical and at A R2,
R1 + R2 = 720,

P = 0.327*R1

in first condition block slides so net moment is zero:
take moment from B,

P*118 + 720*59 = R2*82,

38.586*R1 + 42480 = 82*R2

R1 = 137.33N R2 = 582.67 N

P = 0.327*137.33 = 44.91 N
