66. Numerical and graphical analysis A cross belt connects the 20 cm (10 cm radius) pulley of an electric motor with another 40 cm (20 cm radius) pulley of a circular saw. The electric motor rotates at 1,700 revolutions per minute. 10 cm 20 cm a) Determine the number of revolutions per minute of the saw. b) How does the crossing of the belt affect the saw in relation to the motor? c) Let L be the total length of the belt. Express L as a function of ø, where it is measured in radians. What is the domain of the function? [Hint: Add the lengths of the straight sections of the belt and the lengths of the belt around each pulley.] 66.
