Question

1.

Which, if either, will produce the greater torque: a force applied at the end of a wrench handle perpendicular to the handle or an equal force applied at an angle of 60 degrees to the end of the handle?

Question 1 options:

1. a force applied at the end of a wrench handle perpendicular to the handle

2. an equal force applied at an angle of 60 degrees to the end of the handle?  

3. both are the same

2. A rod has a pivot point on the left end, and a force up on the right end. The torque will be

Question 2 options:

1.positive and clockwise

2.positive and counterclockwise

3.negative and clockwise

4.negative and counterclockwise

Question 2 options:

1.positive and clockwise

2.positive and counterclockwise

3.negative and clockwise

4.negative and counterclockwise

Explanation / Answer

1.
Torque = F*d*sin thetha
Torque is more when thetha is large

So answer:
1. . a force applied at the end of a wrench handle perpendicular to the handle

Because here thetha = 90 degree

2.
F will rotate the rod in counter clockwise direction
It is considered positive by sign convention
Answer:2.positive and counterclockwise
