If R and T are rise and tread of a stair spanning horizontally, the steps are supported by a wall on one side and by a stringer beam on the other side, the steps are designed as beams of width R - T T - R √(R² + T²) R + T TRUE ANSWER : ? YOUR ANSWER : ?
Steel beam theory is used for Design of simple steel beams Beams if shear exceeds 4 times allowable shear stress Doubly reinforced beams ignoring compressive stress in concrete Steel beams encased in concrete TRUE ANSWER : ? YOUR ANSWER : ?
An R.C.C. beam not provided with shear reinforcement may develop cracks in its bottom inclined roughly to the horizontal at 25° 55° 45° 35° TRUE ANSWER : ? YOUR ANSWER : ?
In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 20 mm 10 mm 25 mm 15 mm TRUE ANSWER : ? YOUR ANSWER : ?
In the zone of R.C.C. beam where shear stress is less than 5 kg/cm², nominal reinforcement is provided at a pitch of One and half lever arm of the section One-half lever arm of the section One-third lever arm of the section Lever arm of the section TRUE ANSWER : ? YOUR ANSWER : ?

The load stress of a section can be reduced by Replacing larger bars by greater number of small bars Increasing the total perimeter of bars Replacing smaller bars by greater number of greater bars Decreasing the lever arm TRUE ANSWER : ? YOUR ANSWER : ?
If the tendon is placed at an eccentricity e below the centroidal axis of the longitudinal axis of a rectangular beam (sectional modulus Z and stressed load P in tendon) the stress at the extreme top edge Is increased by PZ/e Is decreased by Pe/Z Remains unchanged Is increased by Pe/Z TRUE ANSWER : ?
