The pin - connected rigid rods AB and BC are inclined at theta =
30 when they are unloaded. When the force P is applied theta
becomes 30.2. Determine the average normal strain developed in wire
AC.
Q.1. (10 Marks) The rigid bar AB is supported by the pin-connected rod BC that has a diameter of 25 mm and is made of A-36 steel (E = 200 GPa). Determine the magnitude of w (kN/m) that is required to displace point B 3 mm downward, 3
The two 4- lb rods EF and HI are fixed (welded) to the link AC
at E . At the instant θ = 30 ∘ link AB has an angular velocity ω =
5 rad/s and an angular acceleration a = 8 rad/ s 2 as shown in
(Figure 1).

A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
