Question 1

The flexibility matrix for the beam shown in the figure is:

Question 2

Consider the beam ABCD and the influence line as Shown below. The influence line pertains to

Question 3

Determine the vertical deflection at the free and of a circular cantilevers frame shown in the figure. Take EI = cosnt. = 3200000 N-m2

P = 10kN, R = 2m

Vertical deflection is _______mm (up to one decimal)

Question 4

There is a beam ABC 10 m long which is fixed at end C. The span AB supports a uniform load of 10 kN/m and a point load 50 kN acts at the middle of the span BC. The end C has an anticlockwise rotation and the end A settles down by .

What is the rotation of end B?

Question 5

A rigid bar is suspended by three rods made of the same material as shown in the figure. The area and length of the central rod are 3A and L. respectively while that of the two outer rods are 2A and 2L respectively. If a downward force of 50kN is applied to the rigid bar. the forces in the central and each of the outer rods will be

Question 6

Three wires AD, BD and CD having the same cross sectional area and of the same material support a load 100 kN as shown in figure. The tension (in kN) in wire BD is
