Can someone please help me with this problem:

A beam is 16m long and rests on two supports, 10m part. the right support is 4m from the right-hand end. The beam carries a uniformly distributed load of 408 kg/m between the two supports and concentrated loads of 2kN at the left end, 0,153 tons at a point 1.4m from the left and 4kN at the right end.

1. calculate the reaction of the two supports

2. draw a shear-force diagram showing all the main values.

3. determine the max and min shear force from the diagram.
