Objective:
The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces.
Principles being examined:
The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the resultant and then balancing the resultant with an equal and opposite force called the equilibrant. When drawing the different forces we needed to find the angle it made. For the F_1, angle we used the formula α+β, and for the F_2 angle, we used 180-(β+γ). For the second part, in order to find the sum …show more content…
By finding the resultant, which is equal to the sum of the original forces, and then balancing that with the equilibrant, we were able to prove the equilibrium of coplanar forces. We verified this point by using a force table to make sure that our force space diagram matched up with the force table and in fact it did match up. Furthermore, considering our trigonometry computations were very close to that of which we drew on the graph, we can say that not only are our graphs accurate, but we also proved the equilibrium of coplanar forces. In conclusion, when all the forces that are acting upon an object cancel out and make the net force equal to zero, then the object is static and has no
