Question 1

Statement 1 : For selecting a rolled I section for a simply supported beam, along with minimum sectional modulus value of span-depth ratio is kept minimum.
Statement 2 : To control the deflection of beam and keep it within limit, minimum value of span-depth ratio is ensured.

Question 2

Two weights are supported as shown in the figure. Tension in string PQ is ______.

Question 3

A tension member of a truss is made up of ISA 75 x 75x 6. The area of ISA 75 x 75 x 6 is 866 mm² and length of member is more than the length of section available. If single V butt welding is used then the tensile capacity of joint (in kN) is
[Permissible axial tension,

Question 4

The tensile capacity of a plate 140 mm wide and 10 mm thick connected to another plate using 18 mm diameter bolts, such that two bolts occur in one row, is _________ kN.
[Use LSM Method]

Question 5

A particle moves along a curve whose parametric equations are : x=t³ + 2t, y=-3e^-2t and z = 2 sin (5t), where x, y and z show variations of the distance covered by the particle (in cm) with time t (in s). The magnitude of the acceleration of the particle (in cm/s²) at t = 0 is _________ cm²/s

Question 6

A vehicle applies brake and skids through a distance of 60 m, before colliding with another parked vehicle, the weight of which is 75% of former. If distance travelled by both vehicle after collision is 15 m before stopping, then the initial speed (in m/sec) of moving vehicle was
[Assume collision is perfectly plastic, brake efficiency

= 100% and coefficient of friction (f) = 0.55]
