A loaded scow has draft of 6ft in fresh water, when erect. The scow is 20ft wide and 40ft long and 8ft high. The center of gravity of the scow is 6ft above the bottom along the vertical axis of symmetry. What is the max. single weight that can be moved transversely from the center of the scow and unloaded over the side without sinking the scow?

3.11 (B). A beam, 12 m long, is to be simply supported at 2m from each end and to carry a u.d.i. of 30 kN/m together with a 30 kN point load at the right-hand end. For ease of transportation the beam is to be jointed in two places, one joint being situated 5 m from the left-hand end. What load (to the nearest kN) must be applied to the left- hand end to ensure that there is no B.M. at the joint (i.e. the joint is to be a point of contraflexure)? What will then be the bes position on the beam for the other joint? Determine the position and magnitude of the maximum B.M. [114 kN, 1.6 m from r.h. reaction; 4.7 m from 1h. reaction; 43.35 kN m.) present on the beam.

A simple beam, 10 m long carries a concentrated load of 500 kN at the midspan. What is the maximum moment of the beam?
