a) You slightly lean on a table as you push it forward. How does your leaning on the table affect the normal/support force between it and the floor?

b) You pull the table toward you and slightly lift it as you do so. How does your lift of the table affect the normal/support force between it and the floor?

Answer #1

(a)

When the table puch forword by applying the force in horizontal direction than the normal force between the floor and table will not affact because the normal force is equal to the weight of the table.

It will affact when the slidding force is applied at an angle.

(b)

The normal reaction is between the floor and table is equal to the weight of the table

when the table is pulled by the force (F) than the normal reaction between the table and floor will decrease by force F.

When the value of lifting force will more then the weight of the table than the table will lift and the normal reaction becomes zero.

Consider the following scenario. You find yourself having some books with a total mass of 32 kg that you have to move from your bedroom to the door of your apartment using a rope attached to the crate. The coefficient of static friction between the crate and the floor is 0.65, and the coefficient of kinetic friction is 0.45 . (a) Pulling the rope horizontally, what is the minimum force you have to pull with to get the crate to...

You are trying to drag a heavy sleeper-sofa across your floor. The sofa has a mass of 150 kg and the coefficient of static friction between the couch and the floor is 1.08. Being a bright physics student, you realize that you can make this easier by pulling upwards and forwards at the same time rather that just pulling the sofa forwards. If you pull on the sofa at an angle 32? above the horizontal how much force does it...
