Three shafts and four gears are used to form a geartrain which will transmit 7.5 kW from the motor at A to a machine tool at F. (Bear- ings for the shafts are omitted from the sketch.) Knowing that the frequency of the motor is 30 Hz, determine the magnitude of the couple which is applied to shaft (a) AB, (b) CD, (c) EF.
using the principles to developed in chapter 3 on equilibrium, one can determine that the tension in cable AB is 143.4 N. Determine the moment about the x-axis of this tension force acting on point A.
A fully enclosed cylindrical fuel tank with a diameter of 6.00 meters and a height of 8.00 meters has a manufacturing tolerance of +/- 0.04 meteres for each of these dimensions.
A closed system of 0.123kg undergoes a frictionless, quasi-static process along the path PV=C from 100kpa to a final state where the volume is twice the initial volume.
Imagine a virtual expressway having 3 lanes. The administrating agency wants to detect traffic accidents in 5 minutes wherever they occur to dispatch an emergency response unit.
A 1 meter diameter cylindrical mass, M, is connected to a 2 meter wide rectangular gate. The gate is to open when the water level, h, drops below 2.5 meters. Determine the required value for M. Neglect friction at the gate hinge and pulley.
what is the probability that less than 0.5 inches of precipitation will occur in any January? What is the probability that more than 2.5 inches wil
If the coordinate direction angles for F3 are a=120degrees, b=45degrees, y=60degrees, determine the magnitude and coordinate direction angles of the resultant force acting on the eyebolt.
a circular aluminum tube of L=600 mm is loaded in compression by forces P. The outside and inside diameters are d2=75 mm and d1=63mm, respectively. A strain Gage is placed on the outside of the tube to measure normal strains in the longitudinal di..
The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e = 0.85 and the initial velocity 6 m/s.neglect friction. (Theta=70 degrees)
The article "Statistical Evidence of Discrimination" (Journal of the American Statistical Association, 1982, pp.773-783) reported that, prior to 1965 in a southern state, 25% of those eligible to serve on a grand jury were black
A company issues corporate bonds that have a coupon rate of 4%, pays dividends quarterly, and has a term of 10 years. Compute the dividend paid per quarter for each bond.
A piston-cylinder contains 40 kg water of which 20 kg is saturated liquid. The equilibrium pressure of the system is 100 kPa. a) Find the system initial volume b) The water undergoes an isothermal expansion until the pressure reaches 10 kPa.
