Q3/ a) Determine the magnitude T of the tension in the supporting cable and the magnitude of the forces on the pin at A for the jib crane shown. The beam AB is a standard 0.5 m I-beam with a weight of 4.66 kN ?

F1 2m F2 A 3.2m 1.8m AF, = 153 N load and a F, = 99 N are applied to the frame which is supported by pins at A and B. These loads are applied perpendicular to the beams. The two beams AC and BC make a right triangle. You may neglect the weight of the members. Find the magnitude of the force at pin C. For this problem, use the coordinate frame given. 1.5 m 4------ 1.5 m +----- 2.4m

The bars AB and BC of the frame shown are each of length L and connected by a pin at B in addition to the cable DE. For the loading shown, find the tension in cable DE. Given: F1= 489 KN; F2 = 978 KN and e = 60° By Cable D F1 F2 Select one: O A. TDE =472.37 KN OB. TDE =423.47 KN OC. TDE =244.50 KN OD. TDE =325.67 KN L/2 L/2 L/2 LI2

Given: P, = 200 lb, P, = 500 lb Find: The forces in each member of the truss. B P2 4 ft 3 ft 4 ft
