The drilling machine was primarily designed to originate a _____

What is the definition of a screw?

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.

In drilling operation, work should be held by hand.

Floating holder is included in______ method of tool holding devices.

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

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

The following can be used to raise a load except

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

What simple machine combines with itself to make a wedge?

Leverage is the ratio of load arm to effort arm.

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 length of the pin.

Which of the following are not included under planar mechanisms?

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.

All of these are examples of inclined planes except:

The critical value at which crack extension occurs is called

Fulcrum can be located at one end of the lever.

A baseball bat is an example of this class of lever:

What is used to make holes in hard objects

How does a ramp make work easier?
