Final answer:
The questions inquired are rooted in physics, centered around mechanical physics principles like Hooke's Law and bulk modulus. They ask for quantitative calculations of material deformations due to applied forces and tensions.
Step-by-step explanation:
The question appears to be related to physics because it is referring to concepts such as tension in wires, angular displacement, and material stiffness—concepts that are usually covered in high school or college-level physics, especially in the context of mechanics and elasticity.
The specific questions involve calculating the extent of deformation (either bending or stretching) of various materials due to applied forces, such as a tension force in the wire or rope, or a pressure increment in a fluid. The process of solving these problems involves using principles of mechanical physics, such as Hooke's Law for the stretching of wires and poles or the bulk modulus equation for pressure-related volume changes in fluids.
Each problem requires applying a formula where the material's properties, such as tensile strength and elasticity, are integrated with the force or pressure applied to find the resultant deformation, whether it is a bend, stretch, or compression.
