Hi! I need help with the lab! I need a summary and criticism & the questions answered pleasee

Lab 2 Vector Addition Objectives After finishing this experiment you should be able to finds the resultant of adding two vectors by three methods: experimentally, by components, and graphically. Equipment Force Table string 3 pulleys and pulley clamps metric ruler 3 mass hangers protractor 2 sheets of paper mass set Introduction Two forces are applied on the force table by hanging masses over pulleys positioned at certain angles. Then the angle and mass hung over a third pulley are adjusted until it balances the other two forces. This third force is called the equilibrant (Fr) since it is the force which establishes equilibrium Since th system is equ liar um The equilibrant force is not the same as the resultant force (FR). Tre csu tant s The equilibrant balances the resultant, therefore the resultant and the equilibrant have the same magnitude, but they are in opposite directions. That is, the equilibrant vector is negative the resultant vector. 17

Explanation / Answer

Net Force in X direction = 0.49 * cos0 + 0.98 * cos120 + 0.88 * cos270 + 0.88 * cos90

                                      = 0 N

Net Force in Y direction = 0.49 * sin0 + 0.98 * sin120 + 0.88 * sin270 + 0.88 * sin90

                                      = 0.8487 N

Thus, equivalent force =   0.8487 N

Direction of force = 90 degree
