a helical compression spring with squared and ground ends is required to exert a maximum working force of 1000 n and a
Question 1: Find an expression for {density of water at 4°C} if the following are known: {acceleration due to gravity, specific gravity, fluid volume, weight} Question 2: Find the pressure at point B if the following are known:
The blade on a snowplow turns the wet snow through an angle of 120- but off to one side at 30-. If the snow has a density of 500 kg/m3, what power is needed to move the blade at 40 mi/h if it scoops snow that is 15-cm deep and 3-m wide?
A car has an initial speed of 25 m/s with a constant deceleration of 3m/s^2. Determine the velocity of the car when t=4s. What is the displacement of the car during the 4 second time interval? How much time is needed to stop the car?
Beverage in cans 150 mm long and 60 mm in diameter is initially at 27°C and is to be cooled by placement in a refrigerator compartment at 4°e. In the interest of maximizing the cooling rate,
A piston-cylinder device contains helium gas initially at 145 kPa, 20 degrees C, and 0.5 m^3. The helium is now compressed in a polytropic process (PV^n = constant) to 390 kPa and 140 degrees C. Determine the heat loss or gain during this process.
Starting with the differential form of the fundamental entropy equation for dS (see Eq1 below and the total differential for dU as a function of V and T. Assuming N is constant, derive an equation for dS dependent on only dV and dT. Provide Each s..
