Symmetrical shoes will not create moment around the joint The position of the pads with an angle of 90° on the brake where it is placed in the figure is shown in the figure. The brake mechanism is fixed to the ground by the support plate. The disc in the figure rotates clockwise and the friction coefficient of the pads is accepted as 0.491. If a force of 565 N is applied on the arm from the point shown on the figure; a) What is the dimension e shown in the figure so that the shoe does not create a moment around the joint? how much should it be? Calculate. b) Draw free body diagrams of ABC opening lever and both lining levers. c) What is the normal force acting on each pad? How much braking torque occurs? calculate
