Question

A force of G pounds is required to pull an object weighing W pounds up a ra

inclined at a degrees from the horizontal.
Find Gif W=5,100 pounds and o= 31º.
2624.7 lb
2626.7 lb
2628,7 lb

Answer 1

(b) 2626.7 lb

Explanation:

Given

`W = 5100\ lb`

`\theta = 31`

Required

Determine the horizontal pounds (G)

This is calculated using:

`G = Wsin\theta`

`G = 5100 * sin(31^\circ)`

`G = 5100 * 0.5150`

`G = 2626.5`

(b) 2626.7 lb answers the question
