Figure Q3 is a schematic diagram of a structure that support the scoop of an excavator. a. Determine the moment about K, if a 700N force is exerted by BC at C, pointing from C to B. b. Determine the magnitude of the force that BC exerts at C (pointing from C to B), if the hydraulic ram DH exerts 1550 N force at D, pointing from D to H

A force F = 7.45 kN directs from point E (0, 3, 6) to point A (0, 0, 8) and rotates about the DK-axis, where point D (2.5, 6, 4) and point K (2.5, 0, 0). All distances are in meters. Determine the moment produced in kNm.

a) Using the scalar approach, find the moments of F1 about the x-axis, the y-axis, and the z-axis. F1 is in the x-z plane. b) Using the vector approach, find the moment of F2 about an axis coincident with rAB

Problem 1 Four forces act on a bracket as shown in Figure 1. (a) Using graphics, determine the resultant (magnitude and direction) as well as the moment of the resultant about point P. (b) Using rectangular components, determine the resultant (magnitude and direction) as well as the projection of the resultant onto the a-a axis. Hint: set up the graphical scale for both lengths and forces. y 2 KN P(-4 m, 3 m) 8 KN 30 25° 4 KN 200 200 6 KN ---- -X a

An experimental device imparts a force of magnitude F = 57 lb to the front edge of the rim at A to simulate the effect of a slam dunk. Compute the moment of the force F about point O and about point B. The moments are positive if counterclockwise, negative if clockwise. Finally, locate a point Ċ from the base at O to the location on the ground where the force imparts zero moment. The distance d from point O to point Ċ is positive if C is to the right of O, and negative if to the left. Assume a = 36 in., b = 28 in., h = 12 in., H = 10 ft, c = 5, and d = 6.
