Statement (I):Radially sawn timber is usually used in construction.
Statement (II): Radial sawing gives timber of maximum strength among all sawing methods.
Question 2
Purlins are provided in industrial buildings over roof trusses to carry dead loads, live loads and wind loads. As per Is code, what are they assumed to be ?
Question 3
Assertion (A) : Traffic Smog is likely to occur in regions where vehicle mileage is considerable and there is a low incidence of sunlight.
Reason (R) : Traffic Smog is caused by the reaction of oxides of nitrogen and some of the hydrocarbons in presence of bright sunlight.
Question 4
Direction: In the following question consists of two statements Assertion(A) and Reason(R). You have to read the statements carefully and select the answers to these questions using the options below.
Assertion (A): the coefficient of friction is the ratio of limiting frictional force to normal reaction between two bodies in contact and one body is being just sliding on the other. Reason(R): the limiting friction is the maximum value of frictional force which comes into play when a body just begins to slide over the surface of the other body.
Question 5
Which of the following statements are correct regarding vortex flows: where symbols have usual meanings:
(i) In free vortex flow : V α 1/r
(ii) In free vortex flow : V α r
(iii) In forced vortex flow : V α 1/r
(iv) In forced vortex flow : V α r
Question 6
Two identical specimens 4 cm in diameter and 8 cm height of partly saturated compacted soil are tested in a triaxial cell under undrained conditions the first specimen failed at an additional axial load of 720 N. Under a cell pressure of 100 kN/m2. The second specimen failed at an additional axial load of 915 N.
Under a cell pressure of 200 kN/m3.
The increase in volume of the first specimen at a failure is 1.2 ml and it shortens by 0.6 cm at failure is 1.6 ml and it shortens by 0.8 cm at failure. The value of apparent cohesion and angle of shearing resistance is,
Question 7
Statement (I): In concreting for large roof slabs, internal vibrators are preferred. Statement (II): External vibrators consume more energy and disturb the formwork.
Question 8
Which of the following are the properties of ideal column as assumed in Euler’s theory?
i. Perfectly straight column
ii. Elasto-plastic material
iii. Homogeneous and isotropic material
iv. Only axial loads exist
Question 9
A 300 mm thick brick masonary wall mode of modular bricks carries an axial load of 30 kN/m from wall above and an eccentric load of 80 kN/m from RCC floor acting at a distance of 50 mm from the centre live of the wall. The resultant eccentricity is:
Question 10
IRC recommendation on OSD are as follows
I. on divided highways and on roads with one way traffic regulation→OSD = d1 + d2
II. on divided highways with four (or) more lanes IRC suggest that there is need to provide OSD
III. Effect of gradient is not considered while calculating OSD
IV. If OSD can not be provided throughout the length of the road , we provide overtaking zone at certain interval given as
