1. Introduction: Moment is an important concept in mechanics. Momentum is used to help analyze the impact of jet water as it strikes a flat plate. We can calculate the theoretical flow moment of the jet which will help in finding properties like height of water level, weight, experimental & theoretical moment and error in moment caused during the experiment. The main objective of the lab is to prove that by putting different weights and leveling it with respect to 0 and 30 degrees of angle, moment is a linear function. 2. The theoretical and experimental values of the moment in this lab were calculated using the following equations and were recorded in Table 1 in the data section below: Mass Measured Height Measured Submerge Moment Measured Moment Calculated Error in Moment g mm m Nm Nm 113.3980924 64 0.064 0.064 0.222487057 1.052385408 -3.730097206 226.7961848 118 0.118 0.118 0.444974115 0.427106799 0.040153607 340.1942772 92 0.092 0.092 0.667461172 0.701415 -0.050870117 453.5923696 72 0.072 0.072 0.889948229 0.92214 -0.036172633 566.990462 51 0.051 0.051 1.112435286 1.15390125 -0.037274944 680.3885544 28 0.028 0.028 1.334922344 1.407735 -0.054544488 -0.644800964 Mass measured Height Measured Submerge Moment Measured Moment Calculated Error in Moment g mm m Nm Nm 113.3980924 152 0.152 0.175514482 0.192679444 0.03664245 0.809826884 226.7961848 105 0.105 0.121243557 0.385358887 0.34333853 0.109042139 340.1942772

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
