Explanation:
Answer:
Option b) False
Explanation:
The given statement for a prismatic bar having constant area of cross section
is not correct and hence False as the length of the bar is not infinite.
The length of the prismatic bar must be very large in comparison to the thickness and width of the bar but has finite length and is not infinite.
Therefore, the correct statement is:
"In plane stress, a prismatic bar with constant area of cross section has finite length."
Answer:
The surface temperature increases when two bodies are rubbed against each other due to friction.
Explanation:
No object has a perfectly even surface. So, when two bodies with uneven surfaces are rubbed against each other, they experience friction.
Friction is a resistance experienced by the two bodies when they are moved against each other.
The friction between the two surfaces, converts the kinetic energy of the movement to the thermal energy.
Thus, resulting in rise in the surface temperature of the two bodies.
Therefore, when two bodies are rubbed against each other, the surface temperature increases due to friction.
