Chapter 1, Problem 10P

Express the specific weight, in U.S. Customary units(lb / in.3), of a specimen of material that has a density of4500 kg/ m3

ASSIGNMENT Complete the table below with the correct values in two decimal places, but "v" must be in five decimal places. A. Assume g = 30.50 ft/s² and V = 6ft³. v (m³/kg) p (kg/m³) a b с d e f 0.01500 1700 y (kN/m³) 9 m (kg) 125 p (lbm/ft³) 90 W (lb) 270

What volume (in m3) of natural gas would it take to generate 5.94 x 108 J of energy if the energy content of natural gas is 36.9 MJ/m3 [round your final answer to one decimal place]?

Some scientists believe that the collision of one or more large asteroids with the Earth was responsible for the extinction of the dinosaurs. The unit of kiloton is used to describe the energy released during large explosions. It was originally defined as the explosive capability of 1000 tons of trinitrotoluene (TNT) high explosive. Because that expression can be imprecise depending on the explosive's exact chemical composition, the kiloton subsequently has been redefined as the equivalent of 4.186 x 1012 J. In the units of kiloton, calculate the kinetic energy of an asteroid that has the size (box-shaped, 13 x 13 x 25 km) and composition (density, 2.4 g/cm) of an asteroid. Kinetic energy is defined by U. = mv? where m is the object's mass and v is its speed. Objects passing through the inner solar system generally have speeds in the range of 20 km/s. (Express your answer using two significant figures.) Uk = x1011 kilotons

Use the information given in the figure below. When the supporting posts are removed, calculate the magnitude of the following: the torque on each side and the net torque of the balancing beam.

One can change the system energy by work (W) and by heat transfer (Q). In a closed system, this is described by the following relation: AE = Q - W Enter the SI units (abbreviated as expected, for example, m instead of meter) for Q and W in the following format: X, X

Please write the final answer with unit 3.Length and diameter of a bearing are equal (d=L). This bearing should be able to withstand the allowable support force of 80 N. Allowable support tension is 20 N/cm?. Determine the length of bearing.
