For the beam and loading shown, (a) write the equations of the

shear and bending-moment curves, (b) determine the magnitude and

location of the maximum bending moment.

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.
