We can’t perform grinding operation in a drilling machine.

Leverage is the ratio of load arm to effort arm.

If the relative motions of the rigid bodies are in one plane or in parallel planes, then the mechanism is called

A right angled bell-crank is designed to raise a load of 5kN at short arm whose length is 100mm. Also longer arm is of length 500mm. If permissible bearing pressure on pin is 10N/mm² and diameter of the 20mm, find the shear stress in the pin.

All of these are examples of inclined planes except:

Hooke’s universal joint is an example of spatial mechanism.

A bottle opener belongs to which class of the levers.

What 2 simple machines make up a pair of scissors?

The drilling machine was primarily designed to originate a _____

The distance between fulcrum and dead weights is 100mm. Dead weights are of 2945.2N. An effort of 294.52N acts on the other hand. Find the distance between the fulcrum and other end of the lever.

Fulcrum can be located at one end of the lever.

A right angled bell-crank is designed to raise a load of 5kN at short arm whose length is 100mm. Longer arm is of length 500mm. Calculate the reaction or force acting on the fulcrum.

These two simple machines make a screw:

Floating holder is included in______ method of tool holding devices.

The formula for the mechanical advantage of an inclined plane is:

Ball bearing is used to reduce

The following can be used to raise a load except

Tapping attachment is included in_______ method of tool holding devices.

.                       Of a machine is the ratio of distance moved by the effort to distance moved by load
