Final answer:
The statement about interior hung scaffolds is false. The high-voltage wires are not insulated, as air acts as the insulator. To solve the tension problem in cables supporting a scaffold, principles of static equilibrium are used.
Step-by-step explanation:
The statement about interior hung suspension scaffolds is false. These scaffolds are typically platforms suspended by ropes or other non-rigid, overhead support.
True or False: Insulated High-Voltage Wires
The statement about high-voltage wires being wrapped in an insulating material is false. High-voltage wires are indeed held aloft by insulating connectors to prevent current from flowing to the towers, but they are not generally wrapped in an insulating material because they are located high enough to be out of reach, and air itself acts as an insulator.
Physics Problem: Tension in Cables
For the physics problem involving a scaffold, a painter, and painting equipment, we would apply the principles of static equilibrium to calculate the tensions in the cables and the mass of the equipment using the conditions for equilibrium: ΣF_y = 0 (sum of vertical forces) and Στ = 0 (sum of torques).
