Problem-3.6 (a) Find the forces on all members of the cantilever truss shown in the figure when F = 4 tons. (b) Using values found in the forgoing analysis, state the horizontal and vertical components of the pin reaction at E and state the directions in which they act to maintain the truss in equilibrium. Figure for Problem- 3.6. Solution:

16 Equilibrium of a Three-Force Body Consider a rigid body subjected to forces acting at only 3 points. Assuming that their lines of action intersect, the moment of F1 and F2 about the Since the rigid body is in equilibrium, the sum of the moments of F1, F2, and F3 about any axis must be zero.

Three forces F 1 F 2 , and F 3 act simultaneously on a point particle. (c) A particle subject to a vertically downward force of 10 newtons (N) and suspended from a cord (tension 15 N) making an angle of 0.1 rad from the vertical cannot be in equilibrium.

Answer : If three vectors are such that they can be represented by the three sides of a triangle taken in cyclic order then the vector sum of the three vectors will be zero.i.e. Answer : Yes a body can be in equilibrium under the action of a single force, if the force is applied at the center of the body.

Three forces of magnitude F1 = 3.0 N, F2 = 4.0 N and F3 = 6.0 N act at a point. ... for a body to be in translational equilibrium? ... the net external force acting ...

Determine total moment MA of the forces F1 and F2 about the point A. F-3 k F-3 k 3 ft 5 ft 30° 6 ft A a. 65.7 06-657 4.-51.5 O a.s. Determine the direction θ (0° ≤ θ ≤ 180°) of the force F so that it produces (a) the maximum moment about point A and (b) the minimum moment about point A. Compute the moment in each case.

respectively. In this way the given system of forces F1, F2, F3 and F4 is replaced by a system of eight forces applied at points 1, 2, 3 and 4. Since the components BO and OB acting along the action line ob form a pair of equal, opposite and collinear forces, they are in equilibrium and eliminate or neutralize each other and therefore may be removed from the system.

Problem 315 The 300-lb force and the 400-lb force shown in Fig. P-315 are to be held in equilibrium by a third force F acting at an unknown angle θ with the horizontal. . Determine the values of F an Evolution and equilibrium 5. Form and function ... Motion and forces 3. Transfer of energy ... F1-1, F1-2, F1-3, F2-1, F2-2, F2-3, F2-4, F3-1, F2-2, F3-3, F4-1, F4-2 ... A force table has a disc and three or more pulley mechanisms that mount on it for the application of forces. Three or more weights are hung as shown. The strings and frictionless pulleys transmit the three forces F 1, F 2, and F 3 to the ring at the center of the round Plexiglas disc. A vertical short stud is attached to the center of the disc.
