What is a control joint and how does it differ from an expansion joint?
What will be an ideal response?
A control joint is provided in components where most of the early movement (immediately after the construction of the component) takes place due to the shrinkage of the component. Therefore, a control joint is also called a shrinkage joint. An expansion joint is provided in components, where the early movement is due to the expansion of the component.

Assume that the voltage source in Figure P2.49 is now replaced by a DC current source IS, and R0 = 1 ?, R1 = 3 ?, R2 = 2 ?, R3 = 4 A, and IS = 12 A, directed positively upward. Use KVL and Ohm’s law to determine the voltage across each resistor.
