Define velocity ratio of a machine and how it is determined - The velocity ratio (V.R.) of a machine is the ratio of distance moved by the effort to distance…

The mechanism which is used for raising and lowering heavy loads to the desire height by using comparatively small effort is called as hoist mechanism. It is mostly operated with…

By using gear trains, large velocity ratio can be obtained with minimum space. Gears are mechanically strong, so higher loads can be lifted. Gears are used for transmission of large…

Definition A partial motion in motion with uniform acceleration has different velocities at different instants of time. These velocities can be found out by using the relation v = u…

Energy is the capacity to do work. Energy is a scalar quantity. Unit of measurement of energy is Jole, same as that of work. Potential energy: The energy possessed by…

Vacancy of electron created in the valance band of solid due to the upward transition of electron is called hole. In case of semiconductor valance and conduction bands are separated…

Friction is the property of two surfaces is contact by virtue of which each surface resists the relative motion of the other surface. Thus when a body moves or tends…

There are mainly three classification of machine design which as under: Adoptive Design Development Design New Design Adoptive Design In this design the work on existing product with adopt of…
