A force of 3 N stretches a spring by 1 m. A mass of 4 kg is attached to the spring. At t=0 the mass is pulled down a distance 1 m from equilibrium and released with a downward velocity of 0.5 m/s. Assuming that damping is negligible, determine an expression for the position of the mass at time t. Find the circular frequency of the system and the amplitude, phase, and period of the motion.
An epoxy matrix composite containing both HS (such as T-300) carbon fiber and E-glass fiber is to be formulated such that the cost/ kg is to be equal $ 8.00/ kg. It is desired to keep the total fiber volume fractionequal to 60 %. What are the requ..
Estimate the energy that must have been supplied to cause the specimen to reach failure.
Refrigerant R-134a is compressed steadily and adiabatically in a reversible compressor. The volume flow rate entering the compressor is 800 ft3/min.
Whit is the critical crack length in iron according to the Griffith-Orowan equation if surface energy=10^3J/m^2?
A power plant operates a regenerative Rankine cycle with a reheat, one closed and one open feedwater heater and has a net power output of 1.2 x 109 Btu/hr. When the steam exits the boiler it's temperature is 1000°F and its pressure is 1400psi...
how can this goal be achieved? are there alternative solutions which might also be effective?
Discuss the factors beyond crystal structure, quenching and temperature that affect he results of a specimen in a Charpy V notch impact testing.
A uniform circular disk of mass m = 1 kg and radius R = 0:4m rolls down an incline. Suppose the disk starts rolling from rest. Find the speed of the center-of-mass when the disk is 2m down the inclined plane.
the girl at C stands pulls the rope horizontally at a constant speed of 6 ft/s. determine how fast the boat approcahes the pier at the instant the rope lenght AB is 50 ft.
What is the work you get out of each kJ of heat extracted from the basin? Repeat for the case that the water is at 100C. Comment on why efficient car engines run so hot.
100 kg of liquid water at 25C and 50 kg of ice at 0C are placed in an isolated container. (a) (b) (c) Find the initial volume of the liquid-ice mixture, in m3. Determine the volume after all the ice is melted, in m3. Will the temperature of the li..
A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the deflection (the vertical distance between the fluid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.2..
