Problem 7.08. A tower crane prepares to lift a 5 × 10³ kg load with its arm extended 70.0 m from the tower pivot point, a) how far from the tower should the x 104 counter weight extend in the opposite direction to ensure the tower does not topple? Assume the mass of the arms is supported by the structure and not relevant to the placement of the counterweight. b) If the counter weight is fixed at a distance of 15 m from the tower, what is the tension in a supporting cable attached from the tower to the load arm from above, at a distance of 40.0 m and an angle of 25.0°.

backboard Force of the wind, Fw 0.35 m 2.00 m Weight of post arrangement 15° 0.25 m Weight of base A portable basketball set has a base and a post arrangement. The post arrangement consists of a post, backboard, hoop and net. The base can be filled with water to increase stability. The maximum weight of the base is about 810 N and the weight of the post arrangement is 26.0 N. The basketball set may topple over when the wind blows due to the large area of the backboard. a) Determine the minimum force of the wind, F, that will cause the basketball set to be blown over when it is at the angle shown. Ignore the effect of the wind on the base. b) The base is filled with sand instead of water. The density of the sand is greater than the density of the water. Justify what would happen to the value of Fw calculated in part (a). 2.

1) A drawbridge has mass M and length L and is approximately uniform. It has a hinge at the right end, and is being pulled up via a cable (FT) that is pointed 45° up from "“to the right" and is connected at L/3 from the left end.
