For the gear and shaft assembly shown in the following figure, Fc = 750 N. Determine the reaction forces the bearings at locations B
For the gear and shaft assembly shown in the following figure, Fc = 750 N. Determine the reaction forces the bearings at locations "B" and "D" apply to the shaft. z do D Gear 1 50-mm dia. bazius 45 mm 20 30 mm 20 mm Gear 2 24-mm dia. Partial Answer: B = -818.8 N and FC 20 Shaft By = 121.9 N The 1 inch diameter shaft is subjected to the loads shown. Draw the loading diagram showing the "Internal" Forces and Moments/Torques acting on a cut section of the shaft through points "A" and "B". 75 lb 8 in. 3 in. 100 lb 80 lb Partial Answer: M = 640 in lb My = 575 in lb Tx = 240 in lb A small laboratory mixing drum is shown in the following figure. Drum "A" is rigidly attached to gear "B" and is supported by two small rollers at points E and D. Gear "B" is rotated by gear "C" which is rotated by an electric motor. If the motor applies a constant torque of 30 Nm to gear "C", determine the angular velocity of drum "A" (in units of rev/min) after gear "C" rotates through 20 revolutions starting from rest. Gear "C" has a mass moment of inertia Ic 0.7829 kg m2 and the combination of gear "B" = and drum "A" has a mass moment of inertia of IB/A = 9.475 kg m. od 300 mm or looga ade 200 mm EO 150 mm Tc = 30 Nm B A D Answer: WA = 251.5 rpm
