help! how to simulate the torsional stress of a shaft in solidworks

assume  a cylindrical shaft (shown below)is 100 mm long and 60mm diameter, matreial is Alloy steel,how can I simulate the torsional stress of its cross-section in solidworks with 2000KN,(how to execute load,how to set boundary conditions,and how to easily view the result what I want),note that the case is similar to transmission shaft application thanks a lot !
