Question

Accepted Answer

Explaining the process of writing on a blackboard using chalk and showing the distribution of stress in a shaft undergoing torque.

To write on a blackboard, the chalk is pressed against the surface, leaving a mark due to friction
The hardness of the chalk and the roughness of the board surface affect the quality of the writing
When a shaft undergoes torque, stress is distributed along its length according to the torque and the shaft's geometry
The distribution of stress can be shown using a schematic diagram with arrows indicating the direction and magnitude of the stress
The maximum stress occurs at the point of maximum torque, which is usually at the center of the shaft
