C. h/4                                 D. h/6

54. The centre of gravity a T-section 100 mm x 150 mm x 50 mm from its bottom is

A. 50mm                      B. 75mm

C. 87.5mm                   D. 125mm

55. If the resultant of two equal forces has the same magnitude as either of the forces, then the angle

between the two forces is

[A]. 30°                              [B]. 60°

[C]. 90°                              [D]. 120°

56. Reynold's number is the ratio of inertia force to

A. pressure force                       B. elastic force

C. gravity force                         D. viscous force

57. the unit of angular acceleration is

58. If the length of the cable is doubled, its capacitance C will become

[A]. Doubled                          [B]. Half

[C]. One-fourth                       [D]. One-fourth

59. What quantity of charge must be delivered by a battery with a Potential Difference of 110 V to

do 660J of Work?

A. 0.6 C                         B. 6 C

C.60 C                           D.  600 C

Explanation: Q = W / V = 660J / 110V = 6C

60. In case of Short Circuit ______Current will flow in the Circuit.

A. Zero                                B.  Very Low

C. Normal                           D.  Infinite

Explanation:

At the short circuited point, the voltage difference is very low (about Zero) So then put the value in

I = P/V, so if we put V = 0, Then Current will be infinite.

61. A simply supported beam of span L carries a concentrated load W at its mid-span. The maximum

bending moment M is

- WL/4

62. The unit of moment of inertia of an area is

- mm4

63. which of the following is a vector quantity

A. Linear displacement                          B. Linear velocity

C. Linear acceleration                            D. All of these

64. The method of measuring distance by pacing is chiefly used in

[A]. reconnaissance surveys                 [B]. preliminary surveys

[C]. location surveys                            [D]. all of these

65. The height of a water column equivalent to a pressure of 0.15 MPa is

[A]. 15.3 m                            [B]. 25.3 m

[C]. 35.3 m                            [D]. 45.3 m

Explanation:

p = H*W.

p = 0.15 * 10^6 pa,

w = specific weight of water = 9810 N/m3.

i.e., H = (0.15 * 10^6)/(9810) = 15.3 m.
