Asteel column is 3 m long and 0.4 m diameter. it carries a load of 50 mn so that 5.967 mm is elongates more. find the modulus of elasticity. show your work in details, write formulas clearly, and plug in values properly.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
