A wood mallet has a cylindrical head 6 inches long and 3 inches in diameter. If the cylindrical head is 1 inch in diameter how long must it be for the mallet to balance at a point 6 inches from where the handle enters the mallet? (use 40 lb / ft cubed) for wieght of wood.
Lines of levels were run requiring n instrument setups. If the rod reading for each backsight and foresight has a standard deviation δ what is the standard deviation in each of the following level lines?
A jet aircraft is flying in a standard atmosphere at an altitude of 4,000 m at 900 km/hr. The frontal intake area of the jet engine is 0.80 m2. The engine exhaust area is 0.56 m2. The temperature of the exhaust gas is 120°C.
There are 3 forces acting on the ring. using the non vector approach, determine the resultant force of only the 150 Ib and 100 Ib forces. Also calculate the angle between the resultant force and the positive x axis.
What mass (in grams) of steam at 100°C must be mixed with 387 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 26.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg, ..
A one-story, 50-m wide X 90-m long manufacturing building is to be built on a site underlain by medium dense to dense silty sand with occasional gravel. This soil probably has better than-average engineering properties and average uniformity.
Assume that there were 1,100,000 vehicles making a 28.5-mi round trip per day, the average vehicle emission rate for VOCs is 1.3 g/VM , and the molecular weight of the VOC emissions from the mobile sources can still be represented by that of metha..
A developer wants to provide access to a new building from a driveway placed 1000 ft upstream of a busy intersection. He is concerned that queues developing during the red phase of the signal at the intersection will block access.
