Consider the following diagram. Find the reactive forces and moments at the fixed point A necessary tomaintain equilibrium if an applied force with components FZ = 50N, FY = 100N, and FX = 0N is exertedat point C in the positive z-direction. Distance a = 1 m and distance b = 0.7 m.
The figure below depicts the tire, axle, and gear of a large tractor. The entire structure is in mechanical equilibrium. Bearings support the rotating axle at points A and C attached to the tractor's frame. A force FD = 5000 lb is applied in the -z direction at point G of a gear with a 3-in radius. The force W = 1000 lb in the +z direction represents a normal force resulting from the weight of the tractor. The force Q acting in the +x direction, represents the traction force between the tire and the ground. The wheel, axle, and gear assembly weigh 150 lb with center of gravity at point D, which lies on the y axis with coordinate yp = -18 in. Points A, C, D (not seen in the figure), and E lie in the yz plane. Point G lies in the xy plane. Questions & Analysis: (a) Draw the FBD for the wheel, axle, and gear assembly if the bearings at A and B resist moments and the bearing at A is a thrust bearing. Label all unknowns. (b) Is the assembly statically determinate or statically…
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 untensioned when the angle θ = 2.0 m and then gives a force F = k s, where s is the elongation 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 = 2.0 kNm^−1, OG = 1.4m, OB = 2.1m, OC = 4.2m, D = (6.5, 2.0) m, g = 9.8ms^−2 a) Identify all the forces that give a moment (m.a.p. 0) and express both the forces and position vectors for the forces' points of attack in component form.
