Determine the required diameter of the pins at a and b if the allowable shear stress for the material is tallow = 100 mpa. both pins are subjected to double shear. a b c 2 kn/m 3 m prob. 1–81 1–82. the steel pipe is supported on the circular base plate and concrete pedestal. if the thickness of the pipe is t = 5 mm and the base plate has a radius of 150 mm, determine the factors of safety against failure of the steel and concrete. the applied force is 500 kn, and the normal failure stresses for steel and concrete are (sfail)st = 350 mpa and (sfail)con = 25 mpa, respectively. r t 100 mm 500 kn prob. 1–

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
