Apurple beam is hinged to a wall to hold up a blue sign. the beam has a mass of mb = 6.7 kg and the sign has a mass of ms = 17.2 kg. the length of the beam is l = 2.78 m. the sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. the angle the wire makes with the beam is θ = 33.9°.
what is the tension in the wire? what is the net force the hinge exerts on the beam? the maximum tension the wire can have without breaking is

t=936 n. what is the maximum mass sign that can be hung from the beam?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
