Link (1) Rigid beam B has a cross-sectional area of 400 mm2 and link (2) has a cross-sectional area of 800 mm2. Determine the maximum load P that may by 600 mm 300 mm 1,000 mm (1) applied if the deflection of the rigid beam is not to exceed 20 mm at point C. Figure No. 4

The pin-connected structure consists of a rigid bar ABCD and two axial members. Bar (1) is bronze [E = 92 GPa] with a cross-sectional area of A₁ = 680 mm². Bar (2) is an aluminum alloy [E = 74 GPa] with a cross-sectional area of A₂ = 350 mm². A concentrated load of P = 56 kN acts on the structure at D. Assume L₁=900 mm., L2=600 mm., a=580 mm., b=310 mm., and c=1160 mm. Determine: (a) the normal stresses 01, 02 in both bars (1) and (2). (b) the downward deflection vp of point D on the rigid bar. b Answers: (a) o₁ = (b) VD= i i L₁ L2 (2) B C MPa, 0₂ = mm. i D MPa

Could you please provide a conceptual explanation with this?

The cantilever beam shown is an aluminum pipe that has an outside diameter of 114 mm and an inside diameter of 97.3 mm. A moment of 3 kN-m is applied at the free end. Find the rotation at the free end of the pipe. Neglect the weight of the pipe.
