Here are the one liners from structural analysis, which may need further explanation but due to some restrictions I am not able to submit those explanations here, if you really need them, you can leave a comment with email , and I will reply to you for sure.
a. A bar AB of diameter 40 mm and 4 m long is rigidly fixed at its ends. A torque of 600 Nm is applied at a section of the bar 1 m from end A. The fixing couples Ta and Tb at the supports A and B are 450N-m and 150 N-m respectively.
b. A propped cantilever of span 'l' carries a uniformly distributed load of 'w' per unit run over its entire span. The value of prop reaction to keep the beam horizontal is 3/8(w.l).
c. A two hinged semi-circular arch of radius 'R' carries a concentrated load 'W' at the crown. The horizontal thrust is w/pi (pi =3.14)
