You do not want to distribute the loads over the support
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement "You do not want to distribute the loads over the support" is false. When distributing loads over the support, it helps to evenly distribute the weight or force applied to the support, which can prevent structural damage or failure. By distributing the loads, it reduces the stress on any single point or area, making the structure more stable and secure. Therefore, it is generally desirable to distribute the loads over the support.

You wanna make sure and not have more than 1/2 of the screw jack exposed
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
To ensure stability and proper functioning of a screw jack, it is important to not have more than half of the screw jack exposed. This is because having more than half exposed would lead to an imbalance and reduce the stability of the jack, making it prone to tipping over or collapsing under heavy loads. Therefore, it is necessary to keep the screw jack properly supported and ensure that no more than half of it is exposed to maintain its stability and safety.
