Problem 1.4. A tensile test was conducted on a mild steel bar. The following data was obtained from the test: (i) Diameter of the steel bar (ii) Gauge length of the bar (iii) Load at elastic limit (iv) Extension at a load of 150 kN. (v) Maximum load (vi) Total extension (vii) Diameter of the rod at the failure Determine : (a) the Young's modulus, = 3 cm = 20 cm = 250 kN = 0.21 mm = 380 kN = 60 mm - 2.25 cm. (c) the percentage elongation, and (b) the stress at lastic limit, (d) the percentage decrease in area.

The City Council proposed to utilize a government-owned land with an area of 21,600square meters. One-third of it will be used for a picnic area while the rest of the landwill be planted by mango trees. As the city engineer, you were tasked to determine thefollowing:1. the dimensions of the picnic area with minimum cost of fencing given that area is tobe rectangular and to be fenced off on three sides not adjacent to the highway.2. the number of mango trees that leads to a maximum yield given that if 70 trees areplanted, the average yield per tree will be 300 kilos while the average yield willdecrease by 3 kilos per tree for each additional tree on the same area due toovercrowding   what is the answer for question no. 2?
