Question

relation between coefficient of friction and angle of repose​

Answer 1

Explanation:

Have a go

WHAT YOU NEED: A bowl of water, cork, sewing needle and a compass. 1 of 5.

Rub the needle 50 times along the magnetic strip on a fridge door. ...

Place the magnetised needle onto the piece of cork. ...

Gently place the needle and cork into the bowl of water. ...

The needle will turn and then come to a complete stop.

Answer 2

Answer:

tanα=μ Here α is the angle of friction and μ is the coefficient of limiting friction. The expression for angle of repose is given as: tanθ=μ Here β is the angle of repose and μ is the coefficient of limiting friction. Thus it is proved that angle of friction and angle of repose are equal.
