Tensile strength: Quiz


Question 1: For example, when a ________ draws water from its roots to its upper leaves by transpiration, the column of water is pulled upwards from the top by capillary action, and this force is transmitted down the column by its tensile strength.

Question 2: The ________ is pounds-force per square inch (lbf/inĀ² or psi); oftentimes kilo-pounds per square inch (ksi) are used to shortened the numbers.
United States customary unitsEnglish unitsImperial unitsCanadian units

Question 3: Brittle materials such as concrete and ________ do not have a yield point, and do not strain-harden which means that the ultimate strength and breaking strength are the same.
