Question

Can someone explain this for me ?

would really appreciate it :))

Answer 1

Step-by-step explanation:

Sum the moments about the hinge H. Assume anticlockwise is positive and clockwise is negative.

∑τ = Iα

(20 N) (500 mm) − F (120 mm) = 0

F = 83 N

Pressure = force / area

P = 83 N / 0.0036 m²

P = 23,000 Pa
