Question
U6Q1 A 200 gram mass is placed upon a balance table at (0.3) it would produce a torque about the B) y-axis C) z- axis -axis U6Q2 Where would a 100 gram mass be placed to bring the balance table into equilibrium? A) (0,3) B) (-3,0) C) (0-6) D) (6.0) U6P1 Located on a balance table are the following masses and their positions. 100 gm @(0.4),200gm@(2.-5), 300gm@(3,7) and 400gm(5,0) Determine the total torque about the x and y axis. Determine the location of the center of gravity for these masses. Where would a 1000 gm mass be placed to bring the system into equilibrium? U6P2 An irregular shaped object has a mass of 325 grams and is placed upon a balance table. The table is brought into equilibrium by placing 2 100 gram masses at (2,0) and (0,3). Where on the balance table is the location of the center of mass for the object?Explanation / Answer
U6Q1) Ans (A)
U6Q2) Ans (C)
U6P1) Torque about the x and y axis:
Lx = 1500 gm-in, Ly = 3300 gm-in
Location of the center of gravity:
xcg = 3.3 in, ycg = 1.5 in
Location of mass for equilibrium:
(-3.3, -1.5)
U6P2) (-0.62, -0.92)
