STATICS  Quiz # STS 01

This section consists of quiz covering topics related to introductory course in statics.

 

	Select the most appropriate answer for the following questions.
1	A force of magnitude 60 kN makes an angle of 30° with positive x-axis. Its component about y-axis will be   (i) 34.64 kN                    (ii) 30 kN                             (iii) 40 kN
2	A point P is subjected to two collinear forces F1 and F2 in such a way that it is in equilibrium. If F1 = 6i –  2j + 3k then F2 will be   (i) F2 = – 6 i + 2j – 3k        (ii)  F2 = 2i + 6j + 4k                  (iii) None
3	The position vector for a point P (2,3,4)  is directed from the origin O (0,0,0) of the coordinate axes  towards the point. It can be written as  (i) OP = 2i + 3j + 4k      (ii) OP = 4i + 3j + 2k            (iii) None of these
4	A force of 10 kN is acting as shown in the following figure. Find the moment of the force about P.        (i)   20 kNm                (ii)  10 kNm              (iii)   None of these
5	A force vector  F of  5 units acting at a point is directed towards positive x-axis. It can be represented as (i) F = 5 k                    (ii) F = 5 i                 (iii) F = 5 j
