If a 350 lb. force is applied to the surface of an 5” x 8” plate that weighs 10 lbs., how much pressure will the plate exert on the ground?

9 psi

Explanation:

Pressure in given by force divided by area. Here, area is 5*8=40 and force will be 350+10=360 lb

Pressure, P=360/40= 9 psi

Therefore, the pressure exerted on ground will be equivalent to 9 psi
