A scaffold of mass 60 $\mathrm{kg}$ and length 5.0 $\mathrm{m}$ is supported in a horizontal position by a vertical cable at each end. A window washer of mass 80 kg stands at a point 1.5 $\mathrm{m}$ from one end. What is the tension in ( a) the nearer cable and (b) the farther cable?

Key Concepts

Tension in Cables

Tension in cables is the force transmitted along the cable when it supports a load. By analyzing the system under static equilibrium, the distribution of tension among multiple supporting cables can be determined, ensuring that both the net force and the net moment are balanced.

Center of Mass

For a uniform object, the center of mass is located at its geometric center. This concept allows the entire weight of the object to be assumed to act at a single point when calculating torques and is crucial for solving problems involving weight distribution.

Torque (Moment of Force)

Torque, or moment, is the measure of the force's tendency to cause an object to rotate about a pivot point. It is calculated by multiplying the force by the perpendicular distance from the pivot. In static equilibrium problems, balancing the torques about any point helps determine unknown forces acting on the object.

Static Equilibrium

Static equilibrium refers to the state where an object remains at rest because the net external forces and the net moments (torques) acting on it are zero. In problems like this, the conditions of static equilibrium are used to set up equations that balance all forces in the vertical direction and all torques about a chosen pivot point.
