With the 315-lb cylindrical part P in its grip, the robotic arm pivots about O through the range-45 ≤ 0 ≤ 45° with the angle at A locked at 120°. Determine and plot (as a function of 0) the moment at O due to the combined effects of the 315-lb part P, the 105-lb weight of member OA (mass center at G₁), and the 35-lb weight of member AB (mass center at G₂). The end grip is included as a part of member AB. The lengths L₁ and L2 are 2.3 ft and 1.6 ft, respectively. What is the maximum absolute value of Mo and at what value of 8 does this maximum occur? The moment is positive if counterclockwise, negative if clockwise. After you have the plot, answer the questions. 5 15/01 4 120 G₂ Questions: When 8-35°, Mo= i lb-ft When 8 = -6°, Mo= lb-ft When 8 = 19°, Mo= lb-ft 2 i
The port hull of a catamaran (top view shown) has cleats at points A, B, and C. A rope having 100N force is to be attached to one of these cleats. If the force is to produce the largest possible counterclockwise moment about point O, determine the cleat to which the rope should be attached and the direction the rope should be pulled (measured positive counterclockwise from the positive x direction). Also, determine the value of MO produced. Assume all cleats, point O, and the rope lie in the same plane.
Using the principles to be developed in Chapter 3 on equilibrium, one can determine that the tension in cable AB is 289.8 N. Determine the moment about the x-axis of this tension force acting on point A. Compare your result with the moment of the weight W of the 25- kg uniform plate about the x-axis. What is the moment of the tension force acting at A about the line OB? 0.38 m Mx = Answers: 0.57 m i -74.047 (Mx)w= MOB -63.853 0 A 0.51 m W 25 kg 23⁰ 0.92 m N-m N-m N•m
The light boom AB is attached to a vertical wall by a ball and socket joint at A and supported by two cables at B. A force P is applied at B where P = 19i - 10j kN.Note that the reaction force at A acts along the boom because it is a two-force member. Magnitude of the reaction force at A in kN = 34.8 Determine the magnitude of the moment of P about the x-axis in Nm
Determine the magnitude of the moment of P about the x-axis in Nm.
Calculate the moment Mg of the 895-N force about the bolt at B. Simplify your work by first replacing the force by its equivalent force- couple system at A. The moment is positive if counterclockwise, negative if clockwise. Assume F = 895 N, r= 155 mm, h = 490 mm, 0 = 30% = 38° OC Answer: Mg = i 0 h N-m
Determine the magnitude of the moment of P about the z-axis in Nm.
The young tree, originally bent, has been brought into the vertical position by adjusting the three guy-wire tensions to AB = 6 lb, AC = 14 lb, and AD = 16 lb. Determine the force and moment reactions at the trunk base point O. Neglect the weight of the tree.
