Beam is fixed at one end, spans 21' then goes over a roller support then 6' continues to hang over. there is a point load halfway betwen the supports (10.5') and another at the far end. there is also a distributed load that stretches the entire beam. each point load and distributed load is broken down into part live and part dead load.Find out the best way to solve for max shear and moment in the beam Also need to find what combinations of loads produce the max shear and moment. only live loads can be "turned on or off'
