If both Pand w are normal random variables, what is the probability that the shear force at the fixed end will exceed 5000 lb?

Refer to the beam loaded as shown. What is the value of Ay?
* Your answer is incorrect. A solid plastic rod has a diameter of d = 21 mm and a length of L = 600 mm. An axial load of P = 24 kN is applied to the rod as shown. The elastic modulus is E = 2.6 GPa and Poisson's ratio for this material is v= 0.37. Determine the magnitude of the change in the rod diameter Ad for the given load. Answer: Ad= i -0.21 L mm
