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

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

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 bottom of a light bulb is what type of simple machine?

For drilling operation, the drill rotates with_____ pressure if job is held on earth

What simple machine combines with itself to make a wedge?

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.

Floating holder is included in______ method of tool holding devices.

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.

How many classes of levers are there?

What is the definition of a screw?

A bottle opener belongs to which class of the levers.

Which of the following are not included under planar mechanisms?

These two simple machines make a screw:

Pliers is an example of what class of lever

If the link next to the shortest link is fixed, what type of mechanism is obtained?

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.

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

Planar mechanisms are ___________ dimensional whereas spatial mechanisms are ___________ dimensional.

Mechanical advantage is the ratio of effort to load.
