Question 1
For a beam of square cross-section having one diagonal horizontal and another vertical, which of the following is correct:
Question 2
What will be the deflection at the location 'a' where the load W acts,
W = 45kN
L = 3m, a = 1m,
EI = 4.16×105 N-m2
W = 45kN
L = 3m, a = 1m,
EI = 4.16×105 N-m2
Question 3
The strain gauge measurement of a steel plate indicate the principle strains are 0.003 and 0.001. What is the value of major principle stress in MPa? (E = 200 GPa, μ = 0.33)
Question 4
A brass bar having a cross section of 15 cm2 is subjected to an axial force as shown in the figure. The stress (only magnitude) in the section BC is given is_____MPa.
Question 5
A cantilever beam of square cross-section with side 10mm is subjected to a point load of 1000N at its free end. The length of the beam is 1m and the modulus of elasticity 200GPa. Calculate the bending strain energy stored in the beam (in kJ) _________ kJ
Question 6
Beam A has a width b, depth 
and length L, while beam B has width b/2, depth d and length 2L. While these cantilever beams are acted by a point load W at the free end. The maximum bending stresses in case (A) and (B) are related as:
and length L, while beam B has width b/2, depth d and length 2L. While these cantilever beams are acted by a point load W at the free end. The maximum bending stresses in case (A) and (B) are related as:
