State what is meant by the compressive strength of a material

AI Thread Summary
Compressive strength refers to the maximum stress a material can withstand before yielding or fracturing. It is defined as the force applied per unit area, measured in units of pressure. The discussion clarifies that "strength" indicates the material's ability to resist undesirable outcomes like yielding or shattering under stress. Understanding this concept involves recognizing the relationship between stress and the material's structural integrity. Compressive strength is crucial for assessing material performance in various engineering applications.

1. State what is meant by the compressive strength of a material


3. The answer given in the mark scheme says - (compressive) stress/F/A/pressure AND to
break/yield/shatter

does anyone know what the answer to this question is? i don't really understand! thanks.

"Strength" usually means the amount of stress a material can withstand before something undesirable (like yield or fracture) occurs. Stress is measured in the same units as pressure, or force per unit area. Does this answer your question?
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
