2.24 A block o.1 m square, with 5 kg mass, slides down a smooth incline, 30° below the horizontal, on a film of SAE 30 oil at 20°C that is 0.20 mm thick. If the block is released from rest at t = 0, determine its initial acceleration. Derive an expression for the speed of the block as a function of time. Plot the curve for V(t). Find the speed after o.1 s. If we want the mass to instead reach a speed of 0.3 m/s at this time, find the viscosity u of the oil we would have to use.

We want to design a wagon system like the one below while filling the kiln with coal at the Coke factory inside Kardemir. In this system, we want the wagon to reach a speed of v= 1 m/s in t=2 seconds. It will then shoot at constant speed. How much engine power is required to tow a wagon with W= 500 kgf under these conditions P=? (Losses will be ignored). (The slope angle of the ramp is α= 25 degrees.)
1. Calculate the kinetic energy of a body which has a mass of 5 kg and velocity of 10 m/s. 2. In a non-flow process carried out 5.4 kg substance, there was a specified internal energy decrease of 50 kJ/kg and a work transfer of the substance of 8.5 kl/kg. Determine the heat transfer and a state whether it is gain or loss. 3. A gas is contained in a cylinder with a moveable piston on which a heavy block is placed. Suppose the region outside the chamber is evacuated and the total mass of the block and the movable piston is 102 kg. When 2140 J of heat flows into the gas, the internal energy of the gas increases by 1580 J. what is the distance through which the piston rises? 4. Calculate the increase in internal energy of a gas in a closed system during a process in which of heat is supplied to the system and 400 J of work is produce. 5. Convert the following readings of pressure to kPa, assuming the barometer reads 760 mm Hg. a. 90 cm Hg gauge b. 40 cm Hg vacuum c. 1.2 m H20 gauge
1. Assuming that there are no heat effects and no frictional effects,find the kinetic energy and speed of a 3220lb body after it falls 778 ft from rest. Start with the steady flow equation, deleting energy terms which are irrelevant. Draw a figure or FBD that will support the problem. Explain each step by step formula.

A certain lake is proposed as a landing area for large jet aircraft. The touchdown speed of 100 mph upon contact with the water is to be reduced to 20 mph in a distance of 1500 ft. If the deceleration is proportional to the square of the velocity of the aircraft throug the water, a=-kv^2 , find the value of the design parameter k . This parameter serves as a measure of the size and shape of the landing gears vanes that plow through the water. Also, determine the time elapsed during the spedified interval. (1 mile=5280 ft)
If the rope on the wall suddenly snaps, what will be the acceleration vector and velocity vectors of these masses at 1=1s after the break? N.B.: the strings are assumed to be massless, flexible and inelastic.
Stainless steel (AISI 304) ball bearings, which have been uniformly heated to 850°C, are hardened by quenching them in an oil bath that is maintained at 40°C. The ball diameter is 12.5 mm, and the convection coefficient associated with the oil bath is 1000 W/m².K. (a) If quenching is to occur until the surface temperature of the balls reaches 100°C, how long, in s, must the balls be kept in the oil? What is the center temperature, in °C, at the conclusion of the cooling period? (b) If 10,000 balls are to be quenched per hour, what is the rate at which energy must be removed, in kW, by the oil bath cooling system in order to maintain its temperature at 40°C? Evaluate the properties of the stainless steel (AISI 304) at 500 K. Part A If quenching is to occur until the surface temperature of the balls reaches 100°C, how long, in s, must the balls be kept in the oil? What is the center temperature, in °C, at the conclusion of the cooling period? t = T₁ = i i S °℃
