In a brick making machine, a wide roller 250 mm in dia mounted on shaft E is driven by a motor carrying a pulley A, which is 150 mm in dia. The pulley in turn drives another pulley of 1200 mm dia mounted on a shaft B by an open belt. On the same shaft B a spur gear of 20 T is mounted, which meshes with a spur gear of 160 T mounted on shaft C. The shaft C also carries a spur wheel of 20 T which drives a 30 T gear on shaft E through an idler gear of 112 T mounted on shaft D. Sketch the arrangement and determines the speed reduction. If motor rotates clockwise (viewing from right) at 1440 rpm, determine the sense of rotation of the roller. What is the surface speed of the roller?
