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

Design a IO-ft-long, single-angle tension member to support a live load of 49.5 kips and a dead load of 16.5 kips (VD= 3). The member is to be connected through one leg and only one bolt hole will occur at any cross section. Use A36 steel and limit slenderness to length/300. Design by (a) LRFD and (b) ASD.

 

What is the Load Resistance seen by this Common Emitter amplifier?

(The amplifier is the first stage, and the rest of the circuit is an FM Transmitter. The input is a mono phone plug from a CD player at 5kHz.)
