Question

Static EquilibriumShow on the following graph the force needed for the object at P to be in static equilibrium.

Short answer

The graph is as follows,

Step-by-step solution

Step 1. Given Information

We are given a graph,

Step 2. Showing the forces

It can be seen that the vertical component of ${\mathrm{F}}_2$is approximately equal and opposite to the force ${\mathrm{F}}_4$so they cancel the effect of each other. Similarly the horizontal component of ${\mathrm{F}}_3$cancels the combined effect of $F_1$and horizontal component of $F_2$. Now only vertical component of $F_3$is left out there, therefore an equal and opposite force is required for the object to be in static equilibrium, which is represented by ${\mathrm{F}}_{\mathrm{R}}$.

The graph is as follows,
