College Physics I Laboratory Conditions for Equilibrium-Force Table Purpose To investigate the vector nature of forces n equilibrium. Vectors are ubiquitous in physics. This lab provides ain opportunity to see and manipulate force vectors, and to compare experimental observations to calculations of vector PHSX 206N sums Pre-Lab Exercises You should review this document then complete these exercises before attempting the Pre-Lab Quiz Before you come to lab You may wish to visit the PhET website and play with the vector addition simulation https://phet.colorado.edu/en/simulation/legacy/vector-addition ercise 1 Suppose that a force of 10.0 N is directed outward from the center of the force table through the 130° mark. What are the z and y components of this force? Be sure to include the sign to indicate the direction of the components. Exercise 2 Suppose that the force described in Exercise 1 is present along with one other force and that the two forces sum to zero. If this is the case, what are the magnitude and direction of the second force? xercise Suppose that the force described in Exercise 1 is present along with two other fores one parallel to the r axis (in either the +or x direction and one parallel to the y axis and that the three forces sum to zero leav1ng nonet force. What are the magnitudes and directions of the two additional forces? Exercise 4 Suppose that two 10.0 N forces are present on the ring at the center of the force table: one is directed at +45° and the other at -45° (which is the same as +315°). If you were to add a third force that would result in a stationary ring, what would be its z and y components? What would be its magnitude and direction? Introduction An object is in equilibrium if it is not accelerating: that is, if it is either at rest or moving in a straight line at a fixed speed, relative to an inertial coordinate system. An object is in static equilibrium if it remains at rest Newton's second law of motion relates the total force on any object to the change in the object's velocity. An object in equilibrium will have no total (net) force acting on it Because force is a vector, the total force can be zero only if each vector component separately is zero. This can be expressed as a vector equation or as the equivalent compe equations. A single two-dimensional vector equation A pair of one-dimensional component equations ! | Be careful! The equation F-Fi + F, + F, + = 0 may look like the equations above. But it is a nonsensical equation that attempts to add all the magnitudes together while ignoring the directions. Since all the magnitudes are positive, they can't add up to zero. Pay attention to the subscripts that indicate the vector components. Some of the components st be positive and some negative such that their sum equals zero Conditions for Equilibrium-Force Table 1 of 5 PHSX 20GN

Explanation / Answer

1)

Given force is : F = 10N

Angle th = 130 degrees

The x-component of the force:

Fx = F cos(th) = 10 cos130 = -6.43 N

The y-component of the force:

Fy = F sin(th)

= 10 sin130

= 7.66 N
