1.A 100 lb force vector F is aligned from A to B. Point A is located at the coordinates (2, 2, 2) and point B at (4,5,6). Calculate the moment of F about the y axis.
2.Go to the weather channel web site (www.weather.com)and look up the monthly average temperature for a major metropolitan area and nearby rural area anywhere in the world over a 12 mo. period. Use the data you looked up to estimate the magnitude of the urban heat island effect for that city. Graph your data in two figures, and determine the temperature differences in each month.
The herbicide 2,4,D, is applied to a golf course at a rate of 1.2 kg/ha. The organic matter content of the soil is 1%, bulk density is 1.3 g/cm3, and water content is 0.3.
A gas has a volume of 2.0 liters, a pressure of 1.2 atm, and a temperature of 30 degrees Celsius is heated to 60 degrees Celsius and compressed to a volume of 1.5 liters. What is the new pressure
determine the force exerted by the rider on the seat, the upward normal forces at A and B, and the lateral friction forces at A and B. Even though the bicycle is free to roll, assume that it does not. The bicycle weighs 29 lb with center of gravit..

A pipeline 1200 ft long and 8 in. in diameter has at its inlet point 75ft of available hydraulic energy with respect to the reference level. The velocity in the pipe is 5 fps: the pressure at its end is 12psi.
If the outer ring rotates in the clockwise direction at 7 rpm and the inner ring rotates in the counterclockwise direction at 12 rpm, what is the angular velocity of the carriers and what is the velocity of C, the center of the top carrier.
Each exerts a force of 600 N directed at a t= 20.0° anglerelative to the forward motion of the boat. If the boat moves withconstant velocity, find the resistive force exerted by the water on the boat.
Suppose we want to estimate the average weight of adult males in greater metropolitan Atlanta area. We draw a random sample of 1,000 men from a population of 1,000,000 men and weigh them.
A compression member is subjected to service loads of 165 kipsdead load and 535 kips live load. The member is 26 feet long andpinned at each end. Use A992 steel and select a W14shape.
There are three 18 mm diameter steel bolts that are attached to a plate. The plate can support up to a 110 KN load, and the ultimate shear stress is 360 MPa. Determine the factor of safety for the given design.
