What is cam and its classification?

Several different classifications are used. According the shape cams are radial, face, wedge, cylindrical, spherical, helical, conical, 3 dimensional ,etc. Cam pairs are classified as force closed or form closed. Force closed cam pairs are more common since it is expensive to manufacture form closed cams.

What are the various types of motion of follower?

There are many follower motions that can be used for the rises and the returns.
…
A : Acceleration of the follower.
  • 1 Constant Velocity Motion. …
  • 2 Constant Acceleration Motion. …
  • 3 Harmonic Motion.

What are the different types of cam?

What are the different types of CAM?
  • Acupuncture.
  • Ayurveda.
  • Homeopathy.
  • Naturopathy.
  • Chinese or Oriental medicine.

What is mushroom follower?

Flat follower / Mushroom follower: In a flat follower, the perfectly flat face is in contact with the cam. In this follower, there will be sliding motion between the contacting surfaces but the wear can be considerably reduced by off-setting the axis of the follower.

What are the 4 types of cam?

Cams and followers
  • Circular. Circular cams use an off-centre pivot to cause the follower to move up and down. …
  • Pear. Pear cams are called this as they have the shape of a pear. …
  • Snail or drop. Snail or drop cams have the appearance of a snail shell. …
  • Heart-shaped or constant velocity.

What is cam and cam follower?

Cams. A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion.

What are the two types of motion for human movement?

Most human motion involves a combination of two types of motion: translatory motion, also known as linear motion, and rotational motion, also known as angular motion.

What do you mean by non uniform motion class 9?

If the speed of an object moving along a straight line keeps changing, its motion is called non – uniform.

What is the difference between uniform motion and accelerated motion?

1 Answer. In Uniform Velocity Motion a body will be moving with a constant /unchanging velocity moving in a particular direction and thus acceleration will be zero whereas in Uniform accelerated motion a body will move at constant acceleration and its velocity will keep changing with time at a constant/ steady rate.

How many basic types of motion are there not accounting chaotic motion?

Everything naturally wants to move and change. In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating.

What is difference between speed and velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

What is the difference between uniform and constant acceleration?

Answer: In constant acceleration the body moving in a particular direction does not change its direction whereas in uniform acceleration the particle covers an equal distance in equal duration of time hence in both the situation acceleration of the body is zero.

What is rate of change of velocity?

Acceleration is defined as the rate of change of velocity.

What is the difference between scalar and vector quantities?

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

Why is velocity zero?

When is Velocity Zero? The object has zero velocity when it does not displace with time. The velocity of the object is zero when there is no displacement of the object. The position of the object between two different time intervals remains the same.

Can velocity be negative?

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).

Is time a scalar or vector?

scalars
For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.

Is velocity a vector?

Velocity is a vector quantity. As such, velocity is direction aware. When evaluating the velocity of an object, one must keep track of direction.

Is mass is a vector quantity?

Mass and energy are scalar quantities, while momentum is a vector quantity.

Is temp a vector?

The temperature is not a vector field, because temperature does not have a direction. It only has a magnitude (absolute temperature). The temperature is a scalar field, which has a magnitude at each point in the atmosphere.

Is time a tensor?

Time is neither vector nor scalar, it is a tensor.
