I've recieved an answer to this question before, but I don't understand it. We're supposed to use vectors to find the answers. Thank you! This is all the information that's given: A link arm (see figure below) has the mass m and center of gravity / center of mass at point G. The arm is freely articulated at point O. At points A, B and C, respectively, there are attachments for a spring and a rope that runs over a stationary pulley at point D (neglect the dimensions of the pulley). The spring is 2.0 m long in the untensioned position and gives a force F = k s on the arm, where s is the extension / compression of the spring. If the arm is in equilibrium, the sum of all moments of force on the arm must be zero, ie. Sum(Mi) = Sum(ri) × Fi = 0 Data: m = 150 kg, k = 4.0 kNm^−1, OG = 1.4m, OB = 2.8m, OC = 4.2m, D = (7, 3) m, g = 9.8ms^−2 a) Identify all the forces that give a moment (with regards to 0) and express both the forces and position vectors for the forces' points of attack in…

Question 9: Figure 3 shows a mechanical system. The rod (with moment of inertia J) rotates about the pivot at only small rotation angles. As pictured, theta is positive clockwise. Attached is mass m, which moves positive to the right. When stationary in the position shown, all springs are undeflected. Using BOBODDY, find the mathematical model of this system assuming small rotation angle 0. Link, moment of inertia J k3 L₁ 12 5 Ꮎ wwww Figure 3: Mechanical System m k₂ b
Two bars, each weighing 5.1 lb/ft, are welded together as shown in figure below. With A = 4.3 ft and B = 6.2 ft, find I, the moment of inertia with respect to the center of the mass in slug-ft2. A В Figure is from "Engineering Mechanic An Introduction to Dynamics", McGill and King.
Question #3: In the figure below, a 100 N weight flower pot is suspended by three ropes. The tension in rope AB is three times the tension in ropes AC and AD. Find the dimension “d” on the figure which corresponds to the z-coordinate of point B. Also find the tensions in ropes AB, AC, and AD. Please do each step as I am trying to check my answers. I got to the point of setting the ijk components equal to zero. I'm stuck at multiplying the tension in vector AB times 3.
