A uniform ladder of length 10.0 m and mas 16.0 kg is resting against a vertical wall making an angle of `37^@` with it. An electrician weighing 60.0 kg climbs up the ladder. If the stays on the ladder at a point 8.00 m from the lower end, will be normal force and the force of friction on the ladder by the ground? What should be the minimum coefficient of friction for the electrician to work safely?

Explanation

To solve the problem step by step, we will analyze the forces acting on the ladder and apply the conditions for equilibrium.

### Step 1: Draw the Free Body Diagram
- Draw the ladder resting against the wall at an angle of \(37^\circ\).
- Identify the forces acting on the ladder:
- Weight of the ladder (\(W_L = m_L \cdot g\)) acting downwards at its center (5 m from the base).
- Weight of the electrician (\(W_E = m_E \cdot g\)) acting downwards at a distance of 8 m from the bottom.
- Normal force (\(N_B\)) acting upwards at the base of the ladder.
