The weight of the beam is given by w = (w3wo)/2 + woL, where w3wo is the distributed load over …ĭetermine the resultant moment produced by the forces about point …. To find the reaction at the roller support, use the equation of static equilibrium. For the beam and loading shown, determine the …. (Figure 1) Determine the stretch in spring AD Express your answer to three … The springs are shown in the equilibrium position. Question: Part B Determine the stretch in each spring for for equilibrium of the 1.8-kg block. Solved Part B Determine the stretch in each spring for …. (Note the unit is mm 3, but is not a volume!) One of it's great uses is to find the centroid, which is the average position of all the points of an object: A plane shape cut from a piece of card will balance perfectly on its. First Moment of Area (relative to the bottom line) = 200 mm 2 x 25 mm = 5000 mm 3.
