Answer:
D. 803 lbs
Explanation:
In order to find the compressive stress on all three blocks we first need to find the normal surface area of each:
Surface Area of 1 Block = 3.5 x 3.5
Surface Area of 1 Block = 12.25
Surface Area of all 3 Blocks = A = 3 x 12.25
Area = 36.75
Now, the stress is given by the following formula:
Stress = Force/Area
Stress = 29500 lbs/36.75
Stress = 802.72 lbs
Hence, the correct option will be:
<u>D. 803 lbs</u>
<span>While a utility patent protects the way an invention is used and works, a design patent protects the way it looks.
Patent is a grant from federal government conferring the rights to exclude others from making, using or selling an invention.
There are three types of patents: Utility, design and plant. Only the inventor or inventors together can apply for a patent.</span>
