Consider a reinforced concrete beam that is 250 mm wide and 750 inches deep. The strength of the concrete is given by f'c = 28MPa. Fifty mm. from the bottom of the beam, two diameter 28mm. bars are inserted. The strength of the steel is fy=415 MPa. What is the largest moment that can be applied to the beam before it cracks?
The assembly consists of a 20-in. wooden dowel rod and a tight-fitting steel collar. Determine the distance x̄ to its center of gravity if the specific weights of the materials are γw = 150 lb/ft3 and γst = 490 lb/ft3. The radii of thedowel and collar are shown.
Help me with Solution, Need fast. Do not waste time. A steel beam is installed in a building when the ambient temperature is -12C. If the beam if fixed at it's ends (prevented from expanding/contracting), calculate the stress that will develop in the beam if the ambient temperature rises to +32C. State whether the stress is tension or compression. Assume E 200,000 MPa and \alpha L = 12x10-6 (/\deg C)
Only 100% correct answer will be accepted. Rest will be down voted. Be careful A steel pipe of length L=3.5m, outside diameter d₂ = 0.8m and inside diameter d: 0.6m. The inside of the pipe is a neatly fitted copper rod. The unit is compressed by an axial force P=100 kN. The modulus of elasticity E steel = 300 GPa copper = 117GPa. Determine the following quantities for the pipe: 1) The stress on the pipe? 2) The longitudinal Strain and the subsequent change in length?

Recently, they have had some problems with their steel and look into some failures. The most probable strength of a steel beam is given by 24Y ―0.05 kips where Y is the number of cycles. This value is known to be 25% with 90% confidence.a) How many cycles will elapse before the beam loses 20% of its strength?b) Suppose the cyclic load on the beam is 10 kips. How many cycles will occur before the probability of failure reaches 10%? Assume this can be described by a lognormal distribution.
