A resultant force of 32 000 N acts on a 225 cm2 area at an angle of 44° with respect to a normal to the area due to pressure and friction. The pressure on the area is nearest (in kPa):

a. 23.02
b. 988.0
c. 1023
d. 22.23
e. 1422

Homework Answers

Answer #1

Given resultant force acts at angle 44 degrees to normal

Resultant force = Fr

The normal force acting on the area is =Fn

Pressure acting normal to the force is given by

Area (A)= 225 cm^2

Area = 225 * 10^(-4) mt^2

Option C is correct
