Correct Answer is written below(preferably handwritten solution) . Detailed and complete fbd only please. I will upvote, thank you.
7: The round bar AB in the figure is formed into a quartercircular arc of radius R that lies in the horizontal plane. The bar is built in at
B and carries the vertical force P at end A. Given: P = 3 kN, R = 900 mm and
α = 25°.
1. Calculate the bending moment (kN-m) acting at section C.
2. Calculate the torsional moment (kN-m) acting at section C.
3. If the allowable torsional stress is limited to 65 MPa, calculate the
required minimum diameter of the bar (mm).
ANSWERS: 1.14 kN-m; 0.25 kN-m; 60 mm
