Question

a 200 - pound air handler is to be suspended by four threaded rods with a spring - mounted vibration isolator on each rod. what weight rating (in pounds) of the vibration isolators should be used? o 50 o 75 o 100 o 200

Explanation:

Step1: Determine total weight

The air - handler weighs 200 pounds and is suspended by 4 threaded rods with vibration isolators.

Step2: Calculate weight per isolator

Divide the total weight of the air - handler by the number of vibration isolators. The formula is $W=\frac{200}{4}$, where $W$ is the weight rating of each vibration isolator.
$W = 50$ pounds

Answer:

50
