Tension members MCQ are provided here for candidates who are actively preparing for the GATE Civil Engineering exam 2023 and other Civil Engineering competitive exams. Tension member MCQ can provide a quick overview of the types of questions to be expected in the exams.

Subjects will be better understood by using objective-based MCQ questions and answers. 5 specially picked questions are mentioned here based on the recent pattern in Civil Engineering competitive exams. Attempt and get a detailed answer to each question mentioned in this article.

## Tension member MCQ 1

A tension member, if subjected to possible reversal of stress due to wind, the slenderness ratio of the member should not exceed

1. 180
2. 250
3. 300
4. 350

Solution

As per IS 800:2007, Table no 3 gives the value of maximum slenderness ratio for tension members.

 Type of  member Maximum slenderness ratio A tension member in which reversal of stress due to load other than wind load 180 A tension member normally acting as a tie in roof truss or a bracing system but subjected to reversal stress resulting from the action of wind or earthquake forces 350 Tension member (other than pretensioned member) 400

## Tension member MCQ 2

In a tension member if b is width of plate, t is thickness of plate, p is staggered pitch, g is gauge distance, n is number of rivet holes in zig-zag line, n’  is number of gauge spaces or lines, d is gross diameter of rivets, then the net sectional area Anet of the plate, is

1. Anet =[b-(nd+n'p2/4g)] t
2. Anet =[b-(nd+n'p2/4g)] t
3. Anet =[b-(nd-n'p2/4g)] t
4. Anet =[b+(nd+n'p2/4g)] t

Solution

Net sectional area (Anet )  of tension member is the gross sectional area minus the deduction of hole

Pitch(P)  is the distance between two adjacent rows of rivet parallel to the direction of application of force.

Gauge is the normal distance between two adjacent gauge lines.

## Tension member MCQ 3

Net sectional area of a tension member, is equal to its gross section area

1. Plus the area of rivet hole
2. Divide by the area of rivet hole
3. Multiplied  by the area of rivet hole
4. Minus the area of rivet hole

Answer: A. Minus the area of rivet hole

Solution

The net area (Anet )  at any section is equal to the gross area minus the deduction for rivet holes at that section. The deduction for the hole is the product of the hole diameter and the thickness of the material.

Note:

The net sectional area of the tension member is the gross sectional area of the member minus sectional area of the maximum number of holes.

## Tension member MCQ 4

When a tension member is made of four angles with a plate as a web, the allowance for holes is made as

1. Two holes for each angle and one hole for the web
2. One hole for each angle and one hole for the web
3. One hole for each angle and two holes for the web
4. Two holes for each angle and two holes for the web

Answer: A. One hole for each angle and two holes for the web

Solution

As per IS 800, when a tension member is made of four angles with plate as web, the allowance for holes is made as one hole for each angle and two holes for the web.

## Tension member MCQ 5

When the length of a tension member is too long

1. A wire rope is used
2. A rod is used
3. A bar is used
4. A single angle is used

Answer: A. A bar is used

Solution

A bar is used if the length of a tension member is too long. A rod may be suitable for carrying an amount of tensile load except that the length of the member (bar) should be short. Wire rope is used in the moderate span of the truss bridge.
