Question

L-T, As open beli drive io sed w driven shaft is to b ated or sopped whever desred witho inertering with the driving u 3. The material used for brake tining hould haefficiest of a low the masimom fluctustion of speed 1.9, The soficient of fastustion of speed tor the thywo and the mesn apeed a product 2 ratie d difference 1-10. The masimum fluctuating speed of the flywheel is the a difference of minimum fluctuating of speed and the mean speed difference of the maximum speed and the minimum speed c sum of the maximum speed and the minimum speed sum of minimum fluctuating of speed and the 1-11, when the speed of belt increases. a The coefficient of friction between the belt and pulley increases b. The coefficient of friction between the bett and pulley decreases The power transmited will decreases The power transmitted will increases -12. In a crossed belt drive, lhe shaft,arc arranged parallel and rotates in . direction 1-13. The tension in the slack (loose) side of the belt is the tension in the tight side of the belt. 1-14. All stresses produces in a belt are stresses 1-15. In Centrifugal clutches, if no spring is used, a same 5)opposite less than c. greater than d. double a compressive b. compressive and tensile tensile d shear a The torque transmitted is proportional to the one-third of the speed b. The torque transmitted is proportional to the half of the speed

Answer 1

1-5 , 1-6 QUESTIONS ARE NOT CLEARLY VISIBLE

1-7 ) B ( shafts are parallel and rotates in same direction)

1-8 ) B ( high coefficient of friction )

1-9 ) B ( Ratio )

1-10 ) B ( diff in max and min speeds)

1-11 ) C ( power transmitted will decrease )

1-12) B

1-13 ) B

1-14 ) C ( ONLY TENSILE STRESSES )

1-15 ) IF NO SPRING IS USED TORQUE TRANSMITTED WILL BE ZERO
