Test: Tension Members - 1 - Question 1

Consider the following statements regarding tensile test diagrams for carbon steels with varying carbon contents:
As the carbon content increases
1. the ultimate strength of steel decreases
2. the elongation before fracture increases
3. the ductility of the metal decreases
4. the ultimate strength increases

Which of these statements are correct?

Detailed Solution for Test: Tension Members - 1 - Question 1

Carbon has the maximum influence on the mechanical properties of steel. Iron-carbon alloys containing up to 2 per cent carbon are called carbon steel while those having more than 2% are called cast steel. With increase in carbon the tensile strength of steel increases but the ductility falls.

Test: Tension Members - 1 - Question 3

The order of elongation which a specimen of mild steel undergoes before fracture is

Detailed Solution for Test: Tension Members - 1 - Question 3

For mild steel
(i) Proportional limit (190 - 220) N/mm2
(ii) Yield strength (230 - 250) N/mm2
(iii) Ultimate strength (410 - 530) N/mm2
(iv) Fracture strength (250 - 300) N/mm2
(v) Elongation at fracture (23 - 35)% Thus the order of elongation is 10%

Test: Tension Members - 1 - Question 4

A plate used for connecting two or more structural members intersecting each other is termed as

Detailed Solution for Test: Tension Members - 1 - Question 4

Base plates are provided to distribute the load of a column on greater area.

Test: Tension Members - 1 - Question 5

Which one of the following stresses is independent of yield stress as a permissible stress for steel members?

Detailed Solution for Test: Tension Members - 1 - Question 5

Permissible values
Axial tensile stress = 0.6fy
Bearing stress = 0.75fy
Maximum shear stress = 0.45fy
Stress in slab base = 185 MPa for all type of steels.

Test: Tension Members - 1 - Question 6

An equal angle of area A has been attached to the support by means of a lug angle. If allowable stress in tension is f, what is the load carrying capacity of the member?

Detailed Solution for Test: Tension Members - 1 - Question 6

Strength of member = allowable tensile stress x
Net area of the angle
Net area = Gross Area - deduction for holes.

Test: Tension Members - 1 - Question 7

A tie member consists of ISA 100 × 75 × 8 longer leg is connected to a gusset plate. The gross cross sectional area of connected and unconnected leg are _______ mm2 respectively.

Detailed Solution for Test: Tension Members - 1 - Question 7

Test: Tension Members - 1 - Question 8

Steel of yield strength 400 MPa has been used in a structure. What is the value of the maximum allowable tensile strength?

Detailed Solution for Test: Tension Members - 1 - Question 8

Maximum allowable tensile strength

Test: Tension Members - 1 - Question 9

A steel plate is 300 mm wide and 10 mm thick. A rivet of nominal diameter 18 mm is driven. The net sectional area of the plate is

Detailed Solution for Test: Tension Members - 1 - Question 9

Net sectional area of the plate is given by,
Anet = (B - nd) x t
= [300-1 x (18 + 1.5)] x 10
= 2805 mm2

Test: Tension Members - 1 - Question 10

The capacity of a single ISA 100 x 100 x 10 mm as tension member connected by one leg only using 6 rivets of 20 mm diameter is

The allowable stress is 150 N/mm2

Detailed Solution for Test: Tension Members - 1 - Question 10

The net area of the tension member is given by, 

The angle section is connected by one leg only.
