1 A hydraulic pump generates 240W and supplies hydraulic fluid at a rate of 5.1l/min to a linear actuator which has a bore size of 50 mm and a double piston rod diameter of 20mm. If the efficiency of the system is 85%, determine:
(a) The pressure exerted on the piston
(b) The force on the piston
(c) The velocity pf the piston
2 A hydraulic linear actuator with a bore size of 110mm and a piston rod diameter of 30mm is to transmit a force of 8.8kN and move with a velocity of 12m/min.
Determine:
(a) The power in kW
(b) The fluid pressure
(c) The fluid flowrate
3 (i) in a hydraulic system, fluid is pumped at a rate of 36l/min. The diameter of the main supply is 32mm and at the user point, it is 16mm diameter. Determine the velocity through the pipes.
(ii) If the system in (i) drives a 40mm diameter hydraulic actuator, calculate the speed of the actuator in mm/min.
A solid shaft of diameter d is taken in power transmission. Because of modification of existing transmission system, it is needed to replace the solid shaft by a hollow shaft of th
If the allowable shear stress for each of the 10-mm-diameter steel pins at A, B, and C is tallow = 90 MPa, and the allowable normal stress for the 13-mm-diameter rod is sallow = 15
The Shaft is made of a material with an allowable shear strength of 80 Mpa. a. Develop the torque diagram b. Determine the minimum acceptable diameter of the shaft
