- 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 2.1 cm from the elbow, how much force must the biceps exert to hold a 35 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.A uniform ladder 10.o m long weighing 50.0 N rests against a smooth wall (no frictional force between ladder and wall). If the coefficient of static friction is .360 and makes a 60 degree angle with respect to the horizontal, what is the frictional force and how far along the ladder can a 70.0 kg painter climb before ladder begins to slip?Determine the magnitude of the pin force at A.

What is the tension in the rope?3. Consider the system shown. A 5.00 m beam supports a mass of 3000 kg attached to a cable. The mass of the beam is 1000 kg. Assume that the mass of the beam is uniformly distributed throughout its length. (a) Determine the tension in the cable (b) Calculate the horizontal and vertical components of the force exerted at point O. 5.00m 3000 kg 45.0°
- Look at the figure below. The horizontal beam weighs 200N, Find the tension in the cable if the object hanging on it is 350N. (Note: its center of gravity is at its center)The horizontal beam inFig weighs 190 N, and itscenter of gravity is at its center.Find (a) the tension in the cable and(b) the horizontal and vertical componentsof the force exerted on the beamat the wall.Abbot and Costello are transporting a 0.125m3cubic block along a ramp inclined at 20°. They tied the block under the midpoint of a 3m, 2kg, pole-arm. Abbot is at the lower end of the pole while Costello leads the pair up, holding the other end of the pole. Calculate the upward forces exerted by Abbot and Costello during the transport if the block weighs 1000N.
- Three forces F, = 20 N, F2 = 10 N and F, = 5.0 N act on the structure shown in figure below. A fourth force F, to be applied at a point P on the structure to keep it in equilibrium. The fourth force has two components Fv and Fh. Given that a = 2.0 m, b = 3.0 m and c = 1.0 m, Calculate Fh, Fv and d %3D N Fh = 30N, Fv 5N= ,d = 1.33m OE Fh = 5N, Fv 30N=, d = 1.33m Oc Fh = 10N, Fv 15N=, d= 3m Od.
