3.58 Determine the tension developed in each of the cables, AB, AC and AD required for equilibrium of the 75-kg cylinder. (this problem assigned in MasteringEngineering) QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. 3.67 Three cables are used to support a 700-lb ring. Determine the tension in each of the cables AB, AC and AD for equilibrium. F4-5 Determine the direction of the moment of the force about point O. Neglect the thickness of the member. 4.20 The tongs are used to grip the ends of the drilling pipe P. If a torque (moment) of MP = 730 lb-ft is needed at P to turn the pipe, determine the cable force F that must be applied to the tongs. Set o = 30 . QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. 4.30 If FB = 35 lb and FC = 35 lb, determine the resultant moment about the bolt located at A. 4.36 The wheelbarrow and its contents have a center of mass at G. If F = 90 N and the resultant moment produced by force F and the weight about the axle at A is zero, determine the mass of the wheelbarrow and its contents. (this problem assigned in MasteringEngineering) QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.
