The simple band brake is constructed so that the ends of the friction strap are connected to
Question:
The simple band brake is constructed so that the ends of the friction strap are connected to the pin at A and the lever arm at B. If the wheel is subjected to a torque M, determine the smallest force P applied to the lever that is required to hold the wheel stationary. The coefficient of static friction between the strap and wheel is μs.
Given:
M = 80 lb⋅ ft β = 45 deg
μ s = 0.5 r = 1.25 ft
α = 20 deg a = 1.5 ft
b = 3 ft
M

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.
