Assignment No.2_Non Coplanar Force System_Questions and Answers_2023-24
(Q.1) A force 5 kN is acting along AB where A (0, 0, -1) m and B (5, -2, -4) m. Another force 8 kN is acting along BC where C (3, 3, 4) m. Find resultant of two forces and find moment of resultant force about a point D (0, 3, -2). (Q.2) A force acts at the origin in a direction defined by the angles θ v = 65 o and θ z = 40 o Knowing that the x - component of the force is 750N, determine (i) the other components (ii) magnitude of the force (iii) the value of θ x . Solution: (Q.3) Find the resultant of the spatial concurrent force system concurrent at A(1,0,0) and passing through points B (-1,3,5), C (3,5,7), D (0,4,0). Magnitudes of forces are, F AB = 100 N, F AC = 150 N, F AD = 200 N. (Q.4) Force 5 KN is acting along AB where A(0, 0, -1) m & B(5, -2, -4) m. Another force 8 KN is acting along BC where C...
