A piece of beef tendon 25 cm long and of cross section 7.8mm*13 mm is stretched to a length of 25.19 cm when it supported a vertical load of .96kg. Calculate young's modulus for the tendon
An 80 cm long wire is made by welding a 1.8 mm diameter, 20 cm long copper wire to a 1.8 mm diameter, 60 cm long iron wire at normal room temperature (20 ∘C). When two wires are connected end to end, their resistances add together. The resistivity of copper is 1.68×10−8Ωm and the of iron is 1.00×10−7Ωm. The temperature coefficients are: copper = 0.0039/∘C and iron = 0.0050/∘C. What is the resistance of the iron section of wire?

4. The resistivity of iron at 20°Cis 100n2m, while that of copper is 17.7n2m. You are building the following two conductors, each of length L-m and of square cross-section with the side a -lcm: 1) By joining a 50cm piece of iron and a piece of copper of the same length and same cross section end-to-end; 2) By joining two lm-long pieces of copper and iron side-by-side such that the total cross section of this new conductor is a square...
