2. A uniform ladder weighing 330. N is leaning against a wall. The ladder slips when the angle with the floor is 50.00. Assuming the coefficient of static friction at the wall and the floor are the same, obtain a value for us.
6) The system shown in in equilibrium. A mass of 225 kg hangs from theend of the strut, which is connected by a hinge to the ground and makes anangle of 45 degrees with the ground. The strut has a mass of 45.0 kg. Asupport cable is attached from a wall to the center of the strut and it makesan angle of 70 degrees with the vertical wall. a) Find the tension in the cable holding up the strut, which make anangle of 70 degrees with the wall. b) Find the horizontal and vertical forces exerted on the strut by the hinge.
2. A 3.0-m-long ladder leans against a wall at an angle of 60° with respect to the floor.

a meter log is a uniform bar of mass m = 77 kg. You want to support it at a rest parallel to the ground. so you place it on a triangle support at 33 cm mark and tie it with a rope on the ground at the 28 cm mark. A) draw your own configuration out. calculate the tension of the rope ____ N, downward, upward, right, left, or none and support force provided by the triangle support _______ N, downward, upward, right, left, or none b) suppose a gumdrop (point mass mb = 14.00 kg) hangs on to the meter log at the 91 cm mark How large will the tension be on the rope? ______ N conceptually explain why it should increase, decrease, or stay the same, compared to part A. C) Now with everything including the gumdrop, the triangle support has been moved away from the rope, to the end of the meter log.Explain why the system itself cannot stay balanced anymore, and the rope goes (T→0). Calculate: rotational inertia of the system below. I = _______ kg·m2Calculate the sizes (+ only) of both the…
