A rough plane is inclined to the horizontal at an angle \(\alpha\), where \(\tan \alpha = \frac { 3 } { 4 }\)
A particle \(P\) of mass 2 kg is held in equilibrium on the plane by a horizontal force of magnitude \(X\) newtons, as shown in Figure 2. The force acts in a vertical plane which contains a line of greatest slope of the inclined plane.
- Show that when \(X = 14.7\) there is no frictional force acting on \(P\)
The coefficient of friction between \(P\) and the plane is 0.5
- Find the smallest possible value of \(X\).
