Mechanical Engineering A steam turbine receives hot & pressurized steam from the inlet (port 1 in the figure), produces work, and discharges steam at low pressure and temperature to the outlet (port 2). P1 = 1.5 x (modifier) MPa, T1 = 350 x (modifier) °C. P2 and T2 are given in the figure. The turbine is at a steady state. Kinetic energy and gravitational potential energy of the steam are negligible compared to its thermal energy. q is negligible Turbine w?

a javelin thrower releases their 600-g javelin 2.0 m above the ground traveling at an angle of 30∘∘ above the horizontal. top-rated javelin throwers do throw at about a 30∘∘ angle, not the 45∘∘ you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30∘∘ than they would be able to at 45^\circ$. in this throw, the javelin hits the ground 70 m away. Calculate the initial speed of the throw.

2. Consider a car suspension, modeled as a mass/spring/damper system (mass m, stiffness k, damping b). Suppose the height of the chassis is lo at rest, the height of the terrain below the driver varies as h(t), and the height of the chassis is denoted lo + y(t). (i.e., spring deflection away from rest is y(t) – h(t)). 2 (a) Give the transfer function G(s) = H(s) · = (b) Suppose the ground follows an oscillatory profile h(t) A cos(wx (t)) with magnitude A (in meters) and frequency w (measured in radians per meter).
