Weba) Explain the conditions required for a constant velocity ratio between two joined shafts. You should include a diagram to support your explanation of why the conditions are required. Guidance word count - 150 words b) Examine the use of a flywheel on reciprocating engines. A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds. CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and earth…

WebThe distance of the moon from the center of the Earth is 3,84,000 km. The distance covered by the moon in one revolution is equal to the circumference of the circular path. Hence, the velocity of the motion is V= 2π r/T. V= 2π x 384000 x 1000/2358720=1022 m/s. The velocity of a moon orbiting around the Earth is 1022m/s and is constant. The velocity ratio of a machine is defined as the ratio of the velocity of the effort to the velocity of the load. In other words, it is the ratio of the displacement of the effort to the displacement of the load. For an ideal machine, the velocity ratio value equals the mechanical advantageof the machine. Velocity Ratio is … See more The velocity Ratio Formula is represented by 2 equations listed below. 1) Velocity Ratio = velocity of the effort / the velocity of the load = VE / VL …… (1) 2) Velocity Ratio = displacement … See more Let’s see how the Velocity Ratio value differs in cases of Speed multiplier machines and Force Multipliermachines.
