- A bridge has uniform mass 9500 kg. If a 3200 kg truck stops 8m from one of a 30m bridge, what weight must each end of the bridge support?y T F х F, An object is subjected to three forces as shown in the figure. Assume F1 = 80.0 N and F2 = 95.0 N, what is T if the object is in static equilibrium? Enter a number with three significant digits.When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.4 cm from the elbow, how much force must the biceps exert to hold a 42 N ball at the end of the forearm at distance of 36.0 cm from the elbow, with the forearm parallel to the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
- With three decimal placesWhat's the force on each rope if the person is standing 1.75 m from one end?A hungry bear weighing 735 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see the figure below). The beam is uniform, weighs 200 N, and is 7.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. (a) Draw a force diagram for the beam. (Submit a file with a maximum size of 1 MB.) Choose File No file chosen Goodies This answer has not been graded yet. (b) When the bear is at x = 1.14 m, find the tension in the wire supporting the beam. X Your response differs from the correct answer by more than 10%. Double check your calculations. N Fx When the bear is at x = 1.14 m, find the components of the force exerted by the wall on the left end of the beam.
