A heavy object could be rolled up this simple machine, instead of lifting it straight up. Using this simple machine can save effort, although the object must usually cover more distance if this simple machine is used.

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

A linkage containing a screw pair is an example of

The drilling machine was primarily designed to originate a _____

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.

Nut crackers are examples of what class of lever

In drilling operation, work should be held by hand.

When the load is between the fulcrum and the effort it is 

A rope, a wheel with a groove in it and a weight make up this simple machine. You can pull down on the rope to lift the weight.

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

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

What simple machine combines with itself to make a wedge?

Which mechanism is shown in the given diagram?

In a mechanical system, if the bodies move in a way such that the trajectories of points in the system lie on concentric sphere, then the mechanism is called

Ball bearing is used to reduce

Which of the following device is not used for holding the work in a drilling machine?

How many classes of levers are there?

All of these are examples of inclined planes except:

The critical value at which crack extension occurs is called
