A 5.70kg block hangs from a spring with spring constant 1900N/m . The block is pulled down 6.80 cm from the equilibrium position and given an initial velocity of 1.70m/s back toward equilibrium. What is the frequency of the motion? What is the amplitude? What is the total mechanical energy of the motion?
calculate the transverse modulus of the peek/carbon fiber composite with 30% volume fraction by tow method. the modulus of peek is 3.8 GPa and the modulus of the carbon fiber is 400GPa. assume the reinforcing factor.
A cylindrical bar of aluminum 19 mm (0.75 in) in diameter is to be deformed elastically by application of a force along the bar axis. Using E=10 psi (Modulus of Elasticity), determine the force that will produce an elastic reduction of 1e-4 in. in..
Examine the influence of the vibration on the grain size, microstructure and mechanical properties of aluminium-silicon alloys (Al-Si) during solidification.
a new containment vessel for nuclear waste is being tested by a group of engineersnbspworking for the u.s. department
draw the projections of a rhombus having diagonals 125mm and 50 mm long, the smaller diagonal of which is parallel to both the principal planes, while the other is inclined at 30 to the H.P.
If a person and a wheelchair have a mombined weight of 185 lb how much ideal effort force is required to travel up the ramp? Can you just explain to me what equation I need for this?
What is the total force reaction (magnitude) at pin joint O when the square plate is released from rest? Assume the plate has a uniform thickness.
To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass. Calculate how many pounds of strawberries are needed to make a..
Average pressure at end of stroke? Upsetting force required at the end of the stroke? If friction is neglected, what is the amount of upsetting force?
now consider the cooling process. it takes place in a heat exchanger hx. warm air. at 75 f is flows into one side of
In order to increase production rate a reactor set point was increased from 160 psig to190 psig. The reactor pressure transmitter was recalibrated from 0-200 psig to 0-300 psig.
The velocity at the inlet is controlled so that it changes according to the following expression. V=a-ct^2, where a = 20m/s, c- 0.8m/s. If the tank initially contains 3kg of liquid water, determine the final mass at the end if 4 seconds of flow.
