Question

QUESTION 4 Pressure is a function of force and the area over which that force is applied (P-F/A). Assuming each of the change from 5.7 inches to 14.1 inches as shown, how much diferent, in percent, will the pressure be in sample B compared to nearest whole percent) grey weights shown are identical, and the poat dimensions 84% QUESTION 5 cantilevered beam situation shown: The weight is 50 ibs located 8.98 inches from the wall. What is the bending moment at the brick wal? Units are in b-in; do not include units in your answer. Round your answer to two decimal points 50 lbs

Explanation / Answer

let the weights of the grey weights be F

PA=F/(5.72) = F*0.0307

PB=F/(14.12) = F*5.129*10-3

percent change in the pressure, PA-PB/PA = 83%

weight= mg = 50.016 lbf

moment of force, T= mg*d = 50.016*8.98 = 449.14 lb-in
