Calculate the (a) stress on the wire; (b) strain on the wire; (c) Young s modulus of the material. A load of 500kg is hung from a circular wire 4.00m long, diameter 0.001m, and a Young's modulus of 8.00 x 10^10 N / m^2. By how much does ...
A 10 m long nichrome wire having80Ωresistance has current carrying capacity of 5 A. This wire can be cut into equal parts and equal parts can be connected in series or parallel. What is the maximum power which can be obtain as heat by the wire from a 200 V mains supply? (in kW)...
