M2.2. A beam consists of two sections. Section A has a mass of 5.0 kg and a length of 3.0 m. Section B has a mass of 2.0 kg and a length of 4.0 m. A block of mass 6.0 kg is hanging from the point where sections A and B are joined together. The beam is attached to a hinge on the wall. A rope is joined to the wall at one end and the beam at the other, at the midpoint of section B. Find the magnitude and direction of the force exerted by the hinge on the beam. 70° B 40° hinge

M PRACH Consider the three displacement vectors A = (4î - 3ĵ) m, B = (61 - 7ĵ) m, and C = (-8î + 5ĵ) m. Use the component method to determine the following. (Take the +x direction to be to the right.) (a) the magnitude and direction of the vector D = A + B + C X magnitude Note that all three vectors lie in the xy plane so the sum of these vectors will also lie in the xy plane. m X The angle you give does not put the sum into the correct quadrant.° counterclockwise from the +x axis direction (b) the magnitude and direction of E= -A-B+C magnitude m direction counterclockwise from the +x axis
