1. The beam is supporting a concentrated load due to a 20 tons crane which moves from A to F. What is the maximum shear force due to the crane at support B? Also determine the maximum moment due to the crane at point B and C.
2. A man weighing 80 Kg is moving from point A to Point G in the following wooden bridge. This bridge can be assumed as a beam. Draw the maximum reaction force due to the man's weight at points A and E. Also draw the maximum shear and moment force due to the man's weight at points C,D and F.
3. Draw the moment influence line in rotational spring at points B and the force influence line in the translational spring at point F. (Assume a concentrated force is moving from point A to F).
