A 25 mm diameter circular power transmission shaft is supported by bearing rotation at points C and C. Power from the motor is transferred to the pulling force in the matulle A, and the drive power is then transferred via the shaft to pulle 3 for transmission. Go out to drive the load through the belt as shown in the picture. Let the pulling force in the belt slack side 1. be 20% of the belt pulling force on the pulling side T, show the calculation as follows. 250 Dia Dimensions in mm 270 N 300 Dia a) Belt tensions T, and T g) Reaction force at bang (unc c) Diagram the shear forces, bending moments and torque of the shaft. 4) Determine the maximum noise and maximum quietness produced in the shaft.
