Need to derive equation 3

192 Pre-Lab: Equilibrium (E11-1) Starting with Equation #2, derive EF = N-W,x - Wich - Wright= 0 an equation for the ratio: mleft /mright. Et = + rich Wleft - right Wright = 0 ST = 0 When = Mien 8 AN Wright = Mright 8 ET -+ RIWL - rrwr right Te ( mcg ) = rr ( mrg ) - 'left W SK mjeft imleft Mright I right (E11-2) Which of the following looks like the previous equation? mleft = - right b. mleft left C . mleft = right left d. mleft = g a . mright mright right mright mright left (E11-3) Now, imagine moving the EF = N- Walk - Wien - Wright= 0 location of the pivot point to the left of the center of mass of the meter stick a Et = + rent Wleft - right Wright - I'sck W suk= 0 distance Istk. Derive an equation which represents AN the distance r'left if the masses and other right distance are given. r'left I stk W Ski Given: g = grav.accel. Fright = dist. right mass from pivot I'stk = dist. meterstick center of mass W. from pivot Mleft = mass of left mass + clamp Mright = mass of right mass + clamp mstk = mass of meterstick + clamp I left = Equation #3 Fall 2022 Lab Instructor.
