- 35.0° Dinysics Demos SuDDly Co. The pole is held horizontally by a massless wire under 305 N of tension, connected at a 35° angle. A 8 kg sign hangs from the end of the 4 meter pole. The pole has mass 4 kg. How far away is the wire is attached from the wall? Answer in meters to 3 sig figs.arrow_forwardFind the mass m of the counterweight needed to balance a truck with mass M = 1 500 kg on an incline of θ = 45° (as shown). Assume both pulleys are frictionless and massless.arrow_forwardWhen 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.arrow_forward

Suppose the mass of a forearm with hand is 1.60 kg. If the biceps is connected to the forearm a distance of 2.1 cm from the elbow, how much force must the biceps exert to hold a 37 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?

- The beam and the cable (with a frictionless pulley at D) support an 80 kg load at C. In a FBD of only the beam, there are how many unknowns? What are they? A 2 m- -2 m -1.5 marrow_forwardA 9 m long board that has a mass of 14. Each end is held up by a vertical rope. A 45 kg box sits 1 m from the left end. Find the tension in the rope on the right. Hint: With forces applied at different places, this is a beam problem pick a pivot point measure all distances from the pivot point Apply Στ = 0 Don't forget torque = force x dist, so you need to multiply the masses by g = 9.8 m/s2 If you need more information, apply ΣF = 0arrow_forward
