M- of 160 mm 150 mm 150 mm 400 N 60° 30° 320 N

1. The built-up beam pictured on the right is subjected to an internal moment of M = 75 kNm. a) At which point(s) of the cross-section the normal stress is zero? b) Determine the maximum compressive and tensile bending stress in the beam.

Answer the question quecly please

Find the tension in cables CF and DE and the support reactions at A. The pin at A exerts couples about the x and z axes and forces along the x and z axes on the collar.
