The beam AB has a negligible mass and thickness and is subjected to a triangular distributed loading.
Question:
The beam AB has a negligible mass and thickness and is subjected to a triangular distributed loading. It is supported at one end by a pin and at the other end by a post having a mass mp and negligible thickness. Determine the two coefficients of static friction at B and at C so that when the magnitude of the applied force is increased to P the post slips at both B and C simultaneously.
Given:
mp = 50 kg
P = 150 N
w = 800N/m
a = 2 m
b = 400 mm
c = 300 mm
d = 3
e = 4
F=µN

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
