The essential features of a transmission dynamometer are shown in figure below (all dimension in mm). A is the driving pulley which runs at 600 RPM. B and C are jockey pulleys mounted on a horizontal beam pivoted at D. about which point the compete beam is balanced when at rest. E is the driven pulley and all portions of the belt between the pulleys are vertical. A, B and C are each 300 mm diameter and the thickness and weight of the belt are neglected. The length DF is 750 mm. Find: 1. The value of the weight W to maintain the beam in a horizontal position when 4.5 kW is being transmitted, and 2. The value of W, when the belt just begins to slip on pulley A. the coefficient of friction being 0.2 and maximum tension in the belt 1.5 kN. Driven 11 27-30 Driving pulley 127,

Q: Figure (1) shows a schematic drawing of a countershaft which is part of the conveyor system and supports two belt pulleys (A & B). The belt tensions are parallel for pulley B and inclincd with angle 45° for pulley A. The pulley A reccives a power from a motor and then delivers to conveyor belt through pulley B. All dimensions are in mm. Required: Design the shaft as shown in figure (1) at points O, A, B & E.
