Abbot and Costello are transporting a 0.125m3cubic block along a ramp inclined at 20°. They tied the block under the midpoint of a 3m, 2kg, pole-arm. Abbot is at the lower end of the pole while Costello leads the pair up, holding the other end of the pole. Calculate the upward forces exerted by Abbot and Costello during the transport if the block weighs 1000N.

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.
