Calculate stresses due to slab weight in precast sections given moment due to slab weight is 1200nm of section modulus 667×103?

Correct Answer: 1.8n/mm2
Section modulus Z = 667×103, moment due to slab weight is 1200nm Stresses due to slab weight in the precast sections = (1200000/667×103) = 1.8n/mm2.

Find the deflection due to self weight given that ϕ = 1.6, Ee = 2.6Ece, elastic modulus of concrete is 34×103, gravity is given as 6, self weight is 0.76, Length of the cable is 1000, elastic modulus of concrete is 34×103 , Moment of inertia is 3200×105?

Weight of L is one-fourth of the weight of V. Weight of V is twice of the weight of B. Weight of B is half of the weight of C. Weight of C is thrice of the weight of H. The weight of V is greater than the weight of how many persons among L, B, H and C?

A cc slab of thickness 20 cm is constructed over a base of granular material with a modulus of reaction 10 kg/cm3. The maximum temperature differential between the top and bottom of the slab is found to be 19°C during summer day and night. The spacing between transverse joints is 8 m and the spacing between longitudinal joints is 4 m. The design wheel load is 5100 kg, radius of contact area is 15 cm, Poisson’s ratio is 0.15, modulus of elasticity is 3×105 kg/cm2, the thermal coefficient is 10 ×10-6 /°C and the coefficient of friction is 1.5. Using the above information, find the worst combination of stresses at the edge of the pavement.

If the surface is rough tamped and without links to withstand a horizontal shear stress of 0.6n/mm2 and assuming the moduli of elasticity of precast and insitu cast concrete to be equal the centroid of the composite section is located 110mm from the top of the slab, second moment area of composite section is 2487×105mm4, calculate ultimate shearing resistance?

In an examination, questions were asked in five sections. Out of the total students, 5% candidates cleared the cut-off in all the sections and 5% cleared none. Of the rest, 25% cleared only one section and 20% cleared four sections. If 24.5% of the entire candidates cleared two sections and 300 candidates cleared three sections. Find out how many candidates appeared at the examination?
