he wheel A is used in a textile mill and must be rotated counterclockwise at 4 rad/s. This can be done using a motor which is mounted on the platform at the location shown. If the shaft B on the motor can rotate clockwise 50 rad/s, design a method for transmitting the rotation from B to A. Use a series of belts and pulleys as a basis for your design. A belt drives the rotation of wheel A by wrapping around its outer surface, and a pulley can be attached to the shaft of the motor as well as anywhere else. Do not let the total length of any belt be longer than 6 ft. Also, determine the total cost of materials if any belt costs $2.50, and any pulley costs $2r, where r is the radius of the pulley in inches.
