Strain can be negative. True or False?
A wire has a young’s modulus of 105N/m2, length 1m & radius 3mm. Assuming a uniform cross sectional area, find the radius of wire after it is under a force of 1N from both ends.
A wire with a radius of 5mm is hung freely from the ceiling. A load of 5N is applied to its free end. Find the elongation in the wire if its volume is 7.85*10-5m3 & young’s modulus is 1011N/m2.
