The pump to be used for pumping highly viscous fluids belongs 10 :
(५) screw pump (B) turbine pump
(0 centrifugal pump (D) plunger pump

Cavitation in centrifugal pump can be reduced by :
(५) reducing the discharge 18) reducing the suction head
(©) throttling the discharge _ (D) increasing the fluid velocity.

A direction control valve designated by 110 3/2 implies :
(ಗೆ) 3 position and 2 port (B) & port and 2 positions
(C) 3 supply port and 2 exhaust port (D) 3 exhaust port and 2 supply ports

The function of check valve is :
(ಗೆ) to allow the flow of fluid in one direction only
(B) to allow the flow of fluid on both directions
(C) to regulate the flow
(D) to check the flow

Sequence valves are also called as :
(A) counter balance valve (ए) shuttle valve
(C) throtile valve (D) diverting valves

A simply supported beam of span 10 m carrying a concentrated load of 1000 N at the mid
span will have the maximum bending moment of :

‎യു 5000 Nm‏ مت 10000 جی
‎(൫ 2500 Nm യ 500 Nm‏

‎The ratio of maximum shear stress to avernge shear stress for a beam with circular section is :
(4) 1 (8) 21

‎The maximum shear stress developed on, the surface of a solid cireular shaft under pure

‎torsion is 320 MPa. If the shaft diameter is doubled., then the maximum shear stress
developed corresponds to the same torque will be :

‎(ಯ) 160 Mpa (B) 80MPa
(C) 40 MPa (D) 30 MPa
