A force of 182.6 lb should be applied to lift 700 lb object.

<h3>How to calculate the force?</h3>

Let the force required to lift be F

Total length = 29 in.

Distance of short end from pivot =  in.

Distance from long end = 29-6 = 23 in.

Now Equating moments

F × 23 = 700x6

23F = 4200

F = 4200/23

= 182.6 lb

A force of 182.6 lb should be applied to lift 700 lb object.

34kurt

Answer:

85° (C).

Step-by-step explanation:

35° should go over to the other side of the line:

180 - 35 = 145°

Find angle 1:

145 + 130 + angle 1 = 360°

360° = 275° + angle 1

angle 1 = 360 - 275

angle 1 = 85°

85° which is C is the answer.
