The static friction comes into play at the moment the force is applied.
Write the relation with static friction and normal reaction.

The static friction comes into play at the moment the force is applied. State the laws of limiting friction.

The static friction comes into play at the moment the force is applied. Determine the maximum acceleration of the train in which a box lying on its floor will remain stationary,given that the coefficient of static friction between the box and the train's floor is 0.15 .

Show that the coefficient of the friction is equal to the tan of the angle between the resultant and normal reactions.

Write the relation between moment of inertia and angular momentum.

Static friction opposes impending motion. Write the mathematical equation connecting the limiting value of static friction with normal reaction.

Static friction opposes impending motion. Choose the CORRECT statement: (i)Both kinetic friction and static friction are independent of the area of contact. (ii)Kinectic friction depends on area of contact but static friction do not. (iii)Static friction depends on area of contact but kinetic friction do not. (iv)Both kinetic friction and static friction depend on the area of contact.
