I need help answering these questions, please.

answer the first question then the second, as per bartley policy my 2 questions are FINE to be submitted.

27/. a) The length and area of an aluminum rod are 63.99 cm and 1580 mm2 respectively. The rod is subjected to a stress of 252.25 N/mm2. Take the modulus of elasticity as 1860 MPa. Determine (i) load and strain in the circular rod (ii) diameter of the rod (iii) how much the rod is stretched. (2 Marks)

I need all parts handwritten or I'll dislike listen again all parts handwritten

2. Make ten measurement for the diameter of the spherical ball first with vernier caliper, then micrometer. Then, fill the table with your results.
