Which one is the aim/objective of Experiment 3 "Simple Plane Framework To compare the average values of u for p.1.1.e and wood obtained To verify that the magnitudes and sense of the forces in a plane triangular truss framework agrees with "framework" theory To confirm that a system of three or more concurrent forces can be equilibrated by calculating the magnitude and direction of their resultant and then applying the equilibrant in the opposite direction. i.e. so that the sums of the components \(\sum x = 0\) and \(\sum y = 0\) for the whole system To confirm that three concurrent forces are in static equilibrium when the sums of their x and y components are zero. i.e. \(\sum x = 0\) and \(\sum y = 0\)

'If three coplanar concurrent forces acting at a point be in equilibrium, then each force is proportional to the sine of the angle between the other two. F= R FS Sin & sin 0 sin Y'

a) What can you say about the sum of the x components and the sum of the y components of the forces acting on a body when it is in equilibrium? b) Are the components of a vector unique? Are the components of a force equivalent, in their effect, to the force itself? c) Does the order in which you add two or more vectors affect the resultant of these vectors?

Three forces P,Q and R are acting at a point in the plane, the angle between P and Q & Q and R are 150^∘, and 120^∘ respectively, then for equilibrium (i.e. net force = 0 ), forces P,Q and R are in the ratio A. 1 2 3 B. 1 2 √(3) C. 3 2 1 D. √(3) 2 1
