Topics: Turning Effect of Forces, Density

A uniform rod has a wooden section and a solid rubber handle, as shown in the diagram below.
The length of the handle is l and the length of the wooden section is 4.00 l. The rod balances at a distance of 2.10 l from the rubber end.

Assume that the density of wood is approximately 1.01 g/cm3.
What is the density of rubber?

Topics: Pressure – Hydraulic Press

In the diagram shown below, Syringe A is connected to Syringe B by a connecting tube. Both syringes and the connecting tube are completely filled with an incompressible fluid X. The diameter of the piston in Syringe B is twice the diameter of the piston in Syringe A. If a force F is applied on the piston in Syringe A, the force experience by the piston in Syringe B is

Topics: Forces

A block of wood of mass 2.0 kg is resting on a rough, horizontal surface as shown. If F and f represents the applied force and friction respectively, find the value of F and f in order to produce an acceleration of 2.0 m/s(square).
