Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

A)What is the tire tread's lowest tangential speed, in meters per second, at which the nail will pull free from the tire? (How does gravity affect the net force on the nail at various positions in the the rotation of the tire.)

v= m/s

At what tangential speed, in meters per second, would the nail pull free when it is at the top of the tire? (This is a mildly silly question because the nail would have already pulled free at some other point in the rotation.)

vtop= m/s

: A tire, which is mounted on a car, has a radius of 0.23 m. A nail with a mass of 7.4 g is stuck in the tread of the tire, and it is held there with a
maximum frictional force of 0.87 N. The car has been elevated on a mechanics lift so that the tire is no longer in contact with the pavement.

A large box of mass 11.4 kg sits on a ramp that makes an angle of 30.1 degrees with the horizontal. The surface of the ramp is rough and the coefficients of static and kinetic friction are given as 0.56 and 0,38, respectively. We exert a force up the ramp (parallel to the ramp surface) so that the box does not move. Calculate the maximum and the minimum magnitude of the force we can exert so that the box does not move. Enter the difference between the maximum and the minimum force values here: Fmax-Fmin (in Newtons). On your paper, show all the forces on free-body diagrams, clearly show your work, your derivation and calculations. Make sure to include your physics-based reasoning.
