1. The problem statement, all variables and given/known data a cantilever beam 5 m long with a mass of 100 N/m carries a concentrated load of 1000 N at its free end. The end of the beam is inserted into a wall 0.5 m thick. What are the reaction on the beam. 2. Relevant equations 3. The attempt at a solution My problem is I cannot imagine the location of the unknown reactions of the beam which is inserted into a wall.
