An offset is to be fabricated in a 3/4-inch RMC to extend from the 3/4-inch knockout in the box at the left, over the obstruction at the right, and down onto the surface below. The offset will be pre-positioned using the radius adjustment so that it clears the obstruction. This offset should use either 45° or 30° bends.

a. True
b. False

Answer :

Final answer:

The boy's claim that he must have been pushing with a force of exactly 100 N is false. The force required to push the box up the ramp is determined by the weight of the box and the angle of the ramp, not just the height and length of the ramp.

Explanation:

The statement is b.False

The boy's claim that he must have been pushing with a force of exactly 100 N is false. The force required to push the box up the ramp is determined by the weight of the box and the angle of the ramp, not just the height and length of the ramp. To calculate the force, you need to use trigonometry and the concept of work. Using the given information, the angle of the ramp can be calculated using the height and length of the ramp. Then, the force can be calculated by multiplying the weight of the box by the sine of the angle.
