The area under the stress-strain curve for a material is usually used to estimate the ____
The area under the stress–strain curve represents the energy absorbed per unit volume by a material up to failure.
This energy absorption capacity is known as toughness.
A tougher material can absorb more energy before fracturing.
A simply supported beam of 8 m has two vertical point loads: 10 kN at 2 m from the left support, 10 kN at 6 m from the left support. Using the graphical method, what is the approximate reaction at the left support ?
A simply supported beam of 10 m carries a uniformly distributed load (UDL) of 5 kN/m over its entire span. What is the reaction force at each support?
Choose one of the assumptions for Macaulay's method of slope and deflection?
