The shape of the beam made of U profile ensures safe loading. Find the length c of the overhangs so that it can move. Of the material Safety stress (σç) emn = 50 N / mm2 for tension and compression conditions, (σb) emn = 80 N / mm2. Support spacing of the beam L = 6 m, cross section its dimensions are a = 210 mm, b = 150 mm and wall thickness t = 40 mm. The loading condition is P = 30 kN and q0 = 40 kN / m.

I need the answer as soon as possible

Give me right solution

please recheck your final answer.

Find? someone can help me with this please.

B) A steel rod with a cross sectional area of (12 mm 12 mm) is stretched between two fixed points. the tensil load at 20°C is 2 KN, what will be the stress at 5°C. assume a = 11.7*10 m/(m.°C) and E-200 Gpa.

QU A composite beam is fabricated by bonding a steel bar and a brass bar and is subjected to the bending moment M = 200 N-m. Determine the maximum bending stress in the brass and steel. Given: E, =200 GPa, E, = 100 GPa Brass 20 }o | Jakrtal

Determine the stresses for each segment when the temperature of the rigid bar is -45 degrees celsius. A close fit exists at both of the rigid supports when the temperature is 24 degrees celsius. Use E= 68 GPa and Coefficient of thermal expansion is 11.7 x 10^-6 per degrees Celsius.

Question 3 of 5 -/ 20 E View Policies Current Attempt in Progress A steel [E = 200 GPa] bar (1) supports beam AB. The cross-sectional area of the bar is 580 mm2. If the stress in the bar must not exceed 330 MPa and the maximum deformation in the bar must not exceed 13 mm, determine the maximum load P that may be supported by this structure. Use dimensions of a = 4 m, b 2.4 m, and c = 5.2 m. %3! C (1) a Answer: kN P = Attempts: 0 of 1 used Sub Save for Later B.

SIR, PLS GIVE ME PROPER AND CORRECT SOLUTION WITH DETAIL. THANKS
