Answer:
Explanation:
When force applied to the end of the rod in perpendicular direction then net torque on the rod is given as
Now another force is applied at mid point of the rod at an angle of 30 degree with the rod
so new value of torque is given as
so we have
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
