Question 4

Identify the correct deflected shape corresponding to the loading in the plane frame shown below:

Question 5

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 A?

Question 6

A cantilever of length 4 m carries a load of 4 kN at free end and 6 kN at its center. If EI is the flexural rigidity of the cantilever, then the slope at the free end of the cantilever _____ x 10-3 radian.
[ Teke EI = 14000 kN-m2]

Question 7

A flexible cable weighing 20 N/m hangs between two supports 60 metres horizontally apart. The left support is 10 metres below the right support. The cable also supports a point load of 1000 N at a point 20 metres horizontally from the left support and 4 metres below this support. Assuming that the weight of the cable is spread uniformly on the horizontal span, the maximum tension (in kN) deleloped in the cable is
