Masood, M. Hasan, A. Fornace, L. Sharma, A. Cranked Lever. Operating the shifting lever to multi-shift to a light gear may also cause the outer casing to spring out of the shifting lever. Bell Crank Lever A bell crank lever is an angled Class 1 lever. The design procedure of Hand lever and Foot Lever is same except the magnitude of load applied on the lever.

Based on the forces calculated, materials for pushrods and bell Figure Follow Us On Social Media:. Print page. Examples of levers are: straight tommy bar used to operate screw jack, bell crank lever, rocker arm, lever of lever loaded safety valve etc. Figure P is the applied effort required to overcome load, W. Ratio of load to effort is called Mechanical Advantage and ratio of effort arm length to load arm length is called leverage.

Depending upon the position of load point, effort point and fulcrum, levers are classified into following classes:. Class I Levers. Lever having the fulcrum located between the load point and effort point is called Class I lever.

Examples are rocker arm, bell crank lever etc. Mechanical advantage of such levers is greater than one as effort arm is larger than the load arm.

Class II Levers. Lever having load point located between the fulcrum and effort point is called Class II lever. Lever used in safety valve is an example of lever of this class. The effort arm is larger than the load arm; therefore the mechanical advantage is more than one. Class III Levers. Lever having effort point located between the fulcrum and load point is called Class III lever. The effort arm, in this case, is smaller than the load arm; therefore the mechanical advantage is less than one.
