Satish varma (red one) sitting idle and playing with a magnifying glass, thought to heat the steel rod before him. He did so and after a long time he found temperature of rod increased by 20°c . cross-sectional area of rod is 15m². Help Satish find how much FORCE the rod is exerting on the rigid wall he is sitting.
young's modulus =E
coefficient of thermal expansion of steel α =0.000001/°c
If u get force as integer X, then type answer as X.00 upto two decimals.
