Calculate all reaction and member forces for the truss below. show all work in your extra sheet of paper, allowing plenty of room for fbds and calculations. make sure all work is legible and neat. be sure to list all formulas, substitutions, and solutions clearly. when you have resolved all forces, draw the fbd for the entire structure at the bottom of your graph paper, showing all applied, reaction, and member forces including type of force.

precision = 0.00 drawing not to scale

-negative 575 lbs on joint b
-roller on joint a
-puller on joint c
-6' from joint a to d
- 3' from d to c
-5' from d to b
- 4 joints
-5 members
- 3 reaction forces
-shaped as a triangle bisected by bd

1.what is the measure of angle bac?
2.what is the measure of angle bcd?
3.what is the magnitude and direction of the reaction force at roller joint a?
4.what is the force on member ab?
5.what is the force on member dc?
6.what is the force on member bc?

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg. m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
