Jerk
The rate of change of acceleration is known as "jerk." Find the direction and magnitude of jerk for a particle moving in a circle of radius R at angular velocity ω. Draw a vector diagram showing the instantaneous position, velocity, acceleration, and jerk
where am is the maximum acceleration and 2T is the total time for the trip.
(a) Draw sketches of a(t) and the jerk as functions of time.
(b) What is the elevator's maximum speed?
(c) Find an approximate expression for the speed at short times near the start of the ride, t T.
(d) What is the time required for a trip of distance D?
temperature varies with altitude. the variation in the temperature can be approximated by tt0 -beta z where t0 is the
Calculate the rate of heat loss per foot and the thermal resistance for a 6-in. schedule 40 steel pipe covered with a 3-in. thick layer of 85% magnesia. Superheated steam at 300°F flows inside the pipe (hc = 30 Btu/h ft2 °F) and still air at 60°F is ..
a rigid 2 m3 tank contains air at 160oc and 400 kpa and a relative humidity of 20. heat is removed until the final
A piston cylinder holds air at 80 F and 15 psi. During an adiabatic process the pressure is increased to 165 psi and the entropy generated is 0.15 BTU/lb-R. Determine the isentropic efficiency for this process.
a small air turbine with an isentropic efficiency of 80 should produce 270 kjkgof work. the inlet temperature is 1000 k
a tank of 2m3 volume contains saturated ammonia at a temperature of 40c. innitially the tank contains 50 liquid and 50
a steel shaft has fatigue strength of 300 mpa for 80000 cycles of fully reversed loading. the same shaft fails by
a heat exchanger for cooling electronic components is fabricated with two aluminum plates separated by aluminum fins
to understand the physics of the o-ring we may need to start formulating the problem in a static equilibrium condition.
while water condensate and vapor-X are removed by means not shown in the sketch. At a pressure of 1 bar, fluid-X has a saturation temperature and a latent heat of vaporization of Tsat = 80°C and hfg = 700,000 J/kg, pressure p for the steam, assu..
a certain body is weighed at an elevation of 30000 ft where g32.08 ftsec2 by a spring balance that was calibrated at
If the beam has square cross section of 9 in., on each side, determine the absolute maximum bending stress in the beam.
