All three cables pull down at D. The forces in cables DA and DB are equal and the force in cable DC is 9.87 kN. Calculate the force in cable DA. Express in KN using three significant figures.

Determine all forces acting on member ABC of the linkage shown in Fig. 500 N B 300 mm 250 N 200 mm + 200 mm - 200 mm

3. A 550 kg drawbridge has a hinge at one end and a cable attached to the other. It is stuck in a position where it makes an angle of 30° with the vertical. The cable pulling on the far end of the bridge is horizontal. Find the tension in the cable as well as the vertical and horizontal components of force from the hinge.
