Question

Determine the force P (kN) required to cause pending motion of the plates if the two bolts are

tightened with a tension of 3 kN. Use a coefficient of

friction of 0.31 at each plate surface. Draw appropriate

free body diagram(s). Draw appropriate free body

diagram(s)

Determine the force P (kN) required to cause pending motion of the plates if the two bolts are tightened with a tension of 3 kN. Use a coefficient of friction of 0.31 at each plate surface. Draw appropriate free body diagram(s). Draw appropriate free body diagram(s)

Explanation / Answer

The centre plate has net force = 3*2 = 6 kN

Fric force for 2 surfaces = 2*(6*0.31) = 3.72 kN

P = 3.72 kN
