2- A tensile test specimen of stainless steel alloy having a diameter of 0.495 in. and a gage length of 2 in. was tested to fracture. Stress and strain data obtained during the test are shown in Figure. Determine; a) Modulus of elasticity, b) The proportional limit, c) The ultimate strength, d) The yield strength (0.20% offset), e) The fracture stress, f) The true fracture stress if the final diameter of the specimen at the location of the fracture was 0.350 in.

3. An athlete pushes against an exercise machine with a force that varies with time according to F(1) = 1200 N (1 – kf), where k = 8 s? Also, the velocity of the athlete's legs acting in the same direction as the force acts according to v(t) = 7 m/s² t a. Create a computer generated plot of the power as a function of time. b. Find the maximum power the athlete generates and the time at which maximum power is generated.

Can someone please help me to solve this graphically on CAD as well as analytically. Show all work thank you!
