Issue # 2 - A V-belt from a 10 in. Diameter spindle pulley that rotates at 1800 rpm, to a 36 in. Diameter flat pulley. The wheelbase is 40 "and the throat angle is 40o. The friction coefficient between the belt and the grooved pulley is 0.2 and with the flat pulley it is also 0.2. The cross section of the straps is a trapezoid with parallel sides of 1.5 "and 0.75", with a height between them of 1 ". The weight of this belt is 0.04 lbf / in3, and the maximum allowable tension on each belt is 200 lbf. Determine: a) How many straps are needed. b) The Torque applied in the transmission, c) The Transmitted power. Note: Consider locating the center of gravity of the belt cross section in order to correct the actual pulley diameter as the band on the splined pulley is slightly outward.)

A 150-mm-wide polyamide F-1 flat belt is used to connect a 50-mm-diameter pulley to drive a larger pulley with an angular velocity ratio of 0.5. The center-to-center distance is 2.7 m. The angular speed of the small pulley is 1750 rev/min as it delivers 1.5 kW. The service is such that a service factor Ks of 1.25 is appropriate. (a) Estimate the centrifugal tension Fc and the torque T. (b) Estimate the allowable F1, F2, and Fi. c) Check the...

QUESTION 1 A. Gravel is being dumped from a conveyor belt at a rate of 10 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always the same. How fast is the height of the pile increasing when the pile is 11 feet high? Recall that the volume of a right circular cone with height h and radius of the base r is given by V= 1/3...
