Complete the free body diagram of the arm BCD of the centre-pull bicycle brake system in the figure below: The brake lever supplies the force T at the top pulling upwards on the T red bracket The link cable then transfers this force to the two cranked arms which are identical when mirrored about the central axis. The arms are held to the bicycle frame by the two bolts where the crank turns and pivot on the bolt. This action forces the blue brake block onto the orange rim of the wheel applying a force of For. Due to the limitations of the interface, you should drag the crosshairs Obeside the symbol to the position on the image of the arm BCD where you think a force should act, т Cable Choose the arrow closest in direction=re to the force you think acts at that point. If there is no known direction for the force, then drag the symbol to that location Link п B B/ If a pure couple is acting on the object, drag either the positive u or negative u couple onto the image as appropriate. o C Tyre 9 Forj For Rim n

T The centre-pull brake force calliper is operated by the application of a tension force in the cable from the lever on the handlebars pulling upwards on the red cable hook. This force is transmitted from the cable hook to both of the crank arms (which are identical and pivot on the attachment bolts at C) through the resulting tension in the link cable. The crank arms then apply the normal braking force For to the rim of the wheel. All of the dimensions are vertical (y-direction) or horizontal (x- direction) except for q which is perpendicular to For m Cable Link n Dimension mm IZ 38 B B m 123 0 72 29 lo 22 35 P 9 48 Tyre Ebri bri Rim p Determine the unit vector of the link cable between the cable hook and the crank arm at B: Given that the tension in the brake cable T = 351 N
