Determine (a) the vertical force P that must be applied to the pedal, (b) the corresponding reaction at C . Knowing that the tension in the left-hand portion of the cable is T 1= 800 lb, determine by trigonometry (a) the required tension T 2 in the right-hand portion if the resultant R of the forces exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R. HIBBELER Upper Saddle River Boston Columbus San Francisco New York Indianapolis London Toronto Sydney Singapore Tokyo Montreal Dubai Madrid Hong Kong Mexico City Munich Paris Amsterdam Cape Town Library of Congress Cataloging-in-Publication Data. 103 for the figure and the analysis leading to the linear algebraic Equations (1), (2), and (3) below: 0. Identify: Apply the first and second conditions of equilibrium to the beam. (a) What is the tension in the cable?(b) What is the minimum coefficient of static friction between the beam and the floor required for the beam to remain. The required tension in cable AB is 200 lb. Determine the tension developed in cables AB , AC , and AD required for equilibrium of the 300 - lb crate. In a FBD of only the beam, there are how many unknowns? A) 2 forces and 1 couple moment B) 3 forces and 1 couple moment C) 3 forces D) 4 forces. Determine the vertical components of the forces that must be exerted by the bolts at A and B to maintain the gearbox in equilibrium 600 lb ft 100 lb-ft 7. The 500 kg block does not slide. A rod AB hinged at A and attached at B to cable BD supports 480 720 1200 N. (b)What is the tension when the elevator is decelerating at the rate of 1. A uniform, 250-kg beam is supported by a cable connected to the ceiling, as shown /in Fig. Cable 1 applies a horizontal force to the right of the right of the object and has a tension, T1. 111 Cable AB is 65 ft long, and the tension in that cable is 3900 lb. It's already given to be £200 and forces see X and see. (8) (ii)Predict the tension in each cable for the given Figure. Determine the tension developed in wires and required for equilibrium of the 10-kg cylinder. [548 N] Figure 29 Figure 30 30 The pole is held in place three cables. What is the tension in the cable during this time? (c) The elevator decelerates at a rate of [latex] 0. A rectangular plate is supported by three cables as shown. Determine the moment MO of this tension about point O over the range 0 90. 2 The cable stays AB and AD help support pole AC. If the lift force on a short section of the airfoil is 50lb, compute the mab" nitude of the resultant force R and the angle θ which it makes with the horizontal. 6 Determine the maximum weight of the flowerpot that can be supported without exceeding a cable tension of 50 lb in either cable AB or AC. 25 A rod AB hinged at A and attached at B to cable BD supports the loads shown. A winch puller AB is used to straighten a fence post. The least amount of tension that will snap the cable of 1200N. Determine the magnitude R of this downward force. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when θ = 30°. ABC is a single overhang simply supported beam with span AB=9m and BC=2.
