The wheel has weight WA and rests on a surface for which the coefficient of friction is
Question:
The wheel has weight WA and rests on a surface for which the coefficient of friction is μB. A cord wrapped around the wheel is attached to the top of the homogeneous block of weight WC. If the coefficient of static friction at D is μD determine the smallest vertical force that can be applied tangentially to the wheel which will cause motion to impend.
Given:
WA = 20 lb
μB = 0.2
WC = 30 lb
μD = 0.3
h = 3 ft
b = 1.5 ft
WA т FB NB Wc h/2 Fp Np

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.
