Question 1 (1 point) If a body is in equilibrium the conditions that must be satisfied are (i) the body must be suspended at its centre of gravity/mass, (ii) the resultant force on the body must be zero, (iii) the sum of moments on the body must be zero (i), (ii), and (iii) are correct only (i) is correct only (i) and (iii) are correct only (ii) and (iii) are correct only (i) and (ii) are correct
Question 2 (1 point) A system of forces that produces only rotation is called distributed moment resultant couple
Question 3 (2 points) A uniform bar of weight 100N and length L is held horizontally using two massless and inextensible strings S₁ and S₂. Rigid support T₁-? T-? Bar SI S2 1/2 1/2 The tensions, T, in the strings are OT₁=100N and T2 = ON T₁ = 75N and T₂ = 25N T₁= 50N and T2 = 50N OT₁= 25N and T₂ = 75N
Question 4 (3 points) Determine the position of centroid for the shaded area YA x 6 m 0,0 8m
Question 5 (3 points) 10 N 0.5 m 20 N 0.5 m + RA RB With reference to the diagram, when moments are taken about RA. the sum of the anticlockwise moments is 25 Nm 30 Nm 0.5 m 10 N 0.5 m
