## When a block is placed on a rough inclined plane of inclination 30 degrees?

A block placed on a rough inclined plane of inclination (θ=30∘) can just be pushed upwards by applying a force ′F′ as shown. If the angle of inclination of the inclined plane is increased to (θ=60∘), the same block can just be prevented from sliding down by the application of a force of the same magnitude.

## What is an inclined plane Lesson 30?

An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other. The inclined plane is one of the six simple machines, and it is used as an aid for raising or lowering a load. Objects placed on an inclined plane accelerate due to an unbalanced force.

## What is the formula for rolling on an inclined plane?

v = 2 g h ( 1 + K 2 R 2 ) , where h is the height of the inclined plane, R is the radius of the body and K is the radius of gyration.

## What is the formula of rough inclined plane?

For a body in equilibrium on a rough inclined surface that is acted on only by the weight of and the normal reaction force on the body, it is the case that 𝑚 𝑔 𝜃 = 𝑚 𝑔 𝜇 𝜃 , s i n c o s where 𝜃 is the angle the surface makes with the horizontal, 𝜇 is the coefficient of static friction between the body and the surface, …

## At what angle with an incline plane of inclination 30 a particle should be projected to have maximum range?

Final answer:60∘ Q. A particle is projected from the bottom of an inclined plane of inclination 30∘.

## What are the 3 types of inclined planes?

Answer and Explanation: The three types of inclined planes are ramps, sloping roads, and hills.

## What are 5 examples of an inclined plane?

• Ramps.
• Stairs.
• Slides.
• Anthills.
• Slanted roofs.
• Escalators.

## What is called inclined plane?

An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.

## What is the formula for net force?

The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object. a is acceleration.

## What is the minimum force required to move a block on an inclined plane?

The minimum force required to move a body up on an inclined plane is three times the minimum force required to prevent it from sliding down the plane.

## What is friction force and its direction on block by inclined plane?

When an object is at rest on an inclined plane as shown in the figure the force of friction is static in nature. The direction of static friction is in upward direction as the block has the tendency to move downwards.

## When a block rests on a rough angled inclined surface so how many forces are acting on the block?

There will be three forces acting on the block and that are the gravitational force in the downwards directional, the normal force exerted by the incline and the frictional force along the incline in the upwards direction, as shown in the figure.

## When a block slides down a rough inclined plane with constant velocity?

Since, the block is moving down with a constant velocity it means the acceleration of the body is zero because acceleration is given by the differential of velocity with time and if velocity is a constant, then the result will be zero. So, the net force acting on the body is zero.

## When a block stays in equilibrium on an incline plane it is easiest to push along?

Answer. Answer: Downwards push is easiest . Explanation: It is easiest to push along the inclined plane downwards .

## When a wooden block is moving down an inclined plane What is the direction of the frictional force acting on the block?

We know that block has a tendency to move down on an incline due to the component of weight parallel to incline in the downward direction. Hence, if the component of additional external force is downward, then the induced motion has downward tendency and friction in upward direction.
