3. If you want a safety factor of four for the supports, would you meet it?

(Hint, you will have to determine the maximum loads at A or B to compare

to the ultimate load strength of 30,000 lbs. Think about at which location

on the bridge the forklift will generate the maximum load between A and

B? Obviously, the max load is when the forklift is located on either A or B.

Use one and do the math. Compare your answer to the ultimate load and

find the safety factor. Compare the calculated safety factor to 4, is it safe

or not. Remember, safe means that the calculated safety factor should be

equal or greater than 4)
