# numbre 1 analyze the moment with respect to point A in the column of the point of the fast route assuming that the bridge has a weight w = 100kn and

numbre 1 analyze the moment with respect to point A in the column of the point of the fast route assuming that the bridge has a weight w = 100kn and that passes through point C

number 2 we have the following crane which at its end a mass of 10 tons a) determine the moment with respect to the origin A, b) determine the moment with respect to the tie B, this tie has an angle of 60 degrees with respect to the vertical, the brace measures 3 m, despise the force at point D.

number 3 in the previous exercise you have a mass of 10 tons and a force F = 50kn at point D, mass of 10 tons is far away at 10 meters and force in D at 7 meters away, replace both forces with a system equivalent in A
