Moments and shear force diagram

[harold42]

Hi
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.

How can we help? What is it you don't understand?

To calculate support reactions, I convert the distributed load to a concentrated load.
