Q4) The 50 kg pot in Fig (4), is supported from A by the three cables. Determine the force acting in each cable for equilibrium? B 2m 6m 3m 3m+ D 1⁰ 5m 4m

Explain how agency benefits of a transportation project is estimated? Use a toll highway project to outline your proposed method.

Problem 6 Two cables of the same gauge are attached to a transmission tower at B. Because the tower is slender, the horizontal component of the resultant of the forces exerted by the cables at B is to be zero. Knowing that the mass per unit length of the cables is 0.4 kg/m, determine (a) the required sag h, (b) the maximum tension in each cable. -90 m- A h B 60 m → 3 m Figure Problem 6 с

Question 2 For the singly-symmetrical, open-section, thin-walled structure shown in the Figure Q2, (a) Calculate the second and product moment of area, Ix and Iy. X-axis is horizontal. (b) Assuming a vertical shear force Sy acting through the shear centre (S) for the thin- walled structure, calculate the distance (}) of the shear centre from the wall 3-4. 2 mm 25 mm 15 mm 2 mm 30 mm 2 mm 60 mm Figure Q2
