Question 1

Consider the following parameters with regards to slenderness ratio of a compression member:
1) Material
2) Sectional configuration
3) Length of member
4) Support end conditions
On which of these parameters does the slenderness ratio of a compression member depend?

Question 2

The best-suited rolled steel section for a tension member is

Question 3

A bracket is supported by means of 4 rivets as shown in figure below. Determine the diameter of the rivet if the maximum shear stress is 140 MPa.

Question 4

An unequal angle ISA 100 × 75 × 8 is connected to a 12 mm gusset plate at the end with four numbers of 16 mm diameter bolts. The angle is to be used as a tension member. If longer leg is connected to the gusset plate, then the design strength due to rupture of critical section, which is governed by the formula given below is

[Assume β for the connection = 1.08]

Where, A_nc = Net area of connected leg

A_go = Gross area of outstanding leg

Question 5

T section will be ideal shape of cross section to resist bending for a material which is

Question 6

Statement 1: Shape of kern for a circular section is determined using middle third rule.

Statement 2: When the load is applied at an eccentricity less than D/8 for a circular section, no tensile stresses will be generated in it.

Question 7

A circular beam of 100 mm diameter is subjected to a shear force of 30 kN. The maximum shear stress will be nearly

Question 8

The state of stress at a certain point in a stressed body is as shown in the figure. Normal stress in x-direction is 80 MPa (Tensile) and in y-direction is 40 MPa (compressive).
The radius of the Mohr’s circle for this state of stress will be

Question 9

Two principal tensile stresses of magnitude 40 MPa and 20 MPa are acting at a point across two perpendicular planes. An oblique plane makes an angle of 30 ° with the major principal plane. The normal stress on the oblique plane is

Question 10
