System A contains one particle, x. System B contains two particles, y and z. The three particles are distinguishable. Each of these systems has the same two accessible single-particle states. How many different states are accessible to
(a) system A,
(b) system B,
(c) the combined system?
Design a box that will contain a 4 in. x 6 in. x 3 in. volume. The box should be produced from two pieces of sheet metal and require no tools or fasteners for assembly. Repeat the problem, but design the box from a single sheet of metal.
ball a is released from rest at a height of 40ft at the same time that a second ball b is thrown upward 5ft from the
Find the maximum bending stresses σface and σcore in the faces and the core, respectively, if their respective moduli of elasticity are 4 ×106 psi and 1.5 ×106 psi.
Steam condenses in a 2cm I.D. thin walled tube of 99% aluminium at 10atm pressure. There are circular fins of constant thickness, 3.5cm in diameter, and every 0.5 cm on the outside. The fins are 0.8mm thick and the heat transfer coefficient from them..
A wooden flume is being built to temporarily carry 5000 L/min of water until a permanent drain can be installed. The flume is rectangular, with a 205-mm bottom width and a maximum depth of 250 mm. Calculate the slope required to handle the expecte..
A cylindrical electric resistance heater has a diameter of 1cm and length of 0.25m. When water at 30oC flows across the heater a heat-transfer coefficient of 15W/(m2oC) exists at the surface. If the electrical input to the heater is 5W, what is the s..
Usually each of the three principal parties (the owner, designer, and contractor) prepares a cost estimate at different times during the life of a project. Describe the purpose of each estimate and the impact that estimating errors may have on the..
How many equations do you think are needed to describe this system mathematically? If the system ever came to rest, what would be the deflection of the spring?
