    Analyzing Truss Stability and Forces: A Case Study

    1. demonstrate with a series of sketches that the truss is simple. Find the force in member BE 2. the blurry dimensions: lower lengths left to right: 2 ft, 1 ft, 1ft, 2ft vertical lengths: bottom to top: 2 ft, 1.5 ft, 1.5 ft top length both 3 ft load is 300 lb/ft 3. started by simple inspection...

    Solve Statics Problems: Finding Forces in Members AB, BH, OH"

    1.find the force in members AB BH OH 2. the forces at O is 3000 lb at O, 5000 lb downward on A and 1000 lb -x direction at A. and 7000 lb -y direction at C. reaction forces at D and E are statically indeterminant. 3. sorry for the crappy sketch. I've gotten AB correct taking...

    Statics Problem, force and moment

    1.find the force exerted on member abcd by the pin at b 2.ƩM=0 ƩF=0 3. sorry for the light colors, its from my office onenote. this is what I've got so far, i wanted to make sure I am on the right track or not

    Solve Series RLC Circuit for Capacitor Value

    1. Consider a series RLC circuit. The applied voltage has a maximum value of 160 V and oscillates at a frequency of 53 Hz. The circuit contains a variable capacitor, a 760 Ω resistor, and a 5.7 H inductor. Determine the value of the capacitor such that the voltage across the capacitor is...

    Charged Plate w/ Gaussian Cylinder: Integral E*dA

    1. Consider a uniformly charged conducting plate with an infinite extent, where the sur- face charge density is surf . We introduce a Gaussian surface as a cylindrical pillbox of ra- dius a, half-way submerged into the surface. The figure below shows a chunk of the infinite plate and the...
