Part A In the reactive AC circuit below, find the voltage and its phase in the output voltage. Both hand-calculation and use of multi-sim needed. (Hand Calculation: 20 Marks, Multisim solution: 10 Marks, Total: 30 Marks)
Use Multisim to determine and plot the voltage that would be measured with this voltmeter as a function of the frequency of the sinusoidal source (Vs) as the frequency of this source varies from 1 Hz to 100 kHz.
Elaborate about the relationship between input and output frequencies, taking into account the effect of the coil and the capacitors on resonant frequency. (10 Marks)
a) A simply supported beam is loaded as shown in the diagram. Finding the reaction forces A and B and draw the shear force and bending moment diagram across the beam.
b) Determine the force acting along the axis of each of the three struts needed to support the 500-kg block.
c) The diagram below shows a plane pin-jointed framework. Determine the force in each member of the truss. State if the members are in tension or compression. Assume all members are pin connected. AG = GF = FE = ED.
