Standard sizes for a channel beam 3- The beam shown is cut with an angel of 0 = 60 degrees. If the force acting on the beam is P=250lbf, answer the following questions: (20 pts) a) Calculate N and V components of the force P. (N and V are the normal and tangential components of the force P in n and t directions.) b) Calculate the normal and shear stress acting on the oblique plane The beam has a height of 4" and depth of 2" P Figure 1 N +0 P Figure 2: dimensions for the cross section of the beam 2"
