18:16 X L3 Dynamics Assignment 2 Calculate the mass D placed at 125 mm from the centre of the disc to balance the disc, and where it should be placed by carrying out the following steps; A B C a) complete the table Mass (kg) Radius (mm) Mr (kg mm) Task 1 b) draw the Mr vector polygon to scale c) use the resultant to determine the mass M, and its position relative to A. Problem 4 A centrifugal clutch has four shoes which slide radially in a spider keyed to the driveshaft. Each shoe is pulled back to a stop by a spring when at rest. When the clutch is engaged the shoes make contact with the inner surface of a cylindrical drum keyed to the driven shaft. The clutch is designed to transmit power at a maximum operating speed of N2. The clutch starts to engage at the speed of N. If the centre of gravity of the shoes is R. from the axis of rotation at the point of engagement, each shoe has a mass of 1 kg, and the coefficient of friction between the shoes and the drum is, calculate the total frictional force. If the inside radius of the drum is R calculate the total torque transmitted. Use the attached table to get the parameter values based on your learner number. FC 1 Shoe Lining G Drum Rg Rd Fs Spring Problem 5 A car has a wheelbase of 2.0m (sideways). Its centre of gravity is 0.8m above the ground. Calculate the smallest radius of bend that the car can negotiate without (a) sliding and (b) overturning at a speed of 120km/h. Assume the coefficient of friction between the tyres and the ground is 0.4. Problem 6 Calculate the same values for the car in problem 5 if the bend is banked at an angle of 15.
