Point A is supported by two springs, BC and DE and two cables AB and AD.

Show transcribed image text Point A is supported by two springs, BC and DE and two cables AB and AD. Question 3 25 marks Point A is supported by two springs, BC and DE and two cables AB and AD. Spring BC has a stiffness k = 1500 N/m and spring DE has 300 mm unstretched length. Lengths of cables AB and AD are 700 mm and 800 mm respectively. The structure has the geometry shown in Figure 3 when the vertical downward force at A is 400 N. Assume springs and cables have negligible weights and determine the following: i. Forces in cables AB and AD ii. Unstretched length of spring BC iii. Stiffness of spring DE
