A minus 3.0% street grade and a plus 2.0% street grade intersects at station 8+00 at elevation 1450 feet. It is necessary to pass under an overhead structure at station 9 + 00 with a 16 feet clearance. The elevation of the lowest bottom of the structure is at 1470 feet. Calculate the maximum length (feet) of the parabolic curve required to meet the given conditions.
The wheel of radius r rolls without slipping and has an angular velocity w. Write an expression for the velocity of point A in terms of theta and show that the velocities of A and B are perpendicular to one another
the motorcycle is traveling at 1 m/s when it is at A at the bottom of the ramp. If the speed is then increased at v=0.1 m/s^2, determine its speed and acceleration at the instant t=5s
Assuming the ball experiences a downward acceleration of a = 10-9v2 when in the water, determine the velocity of the ball when it strikes the bottom of the lake.
The steel ball is suspended from the accelerating frame by the two cords A and B. Determine the acceleration a of the frame which will cause the tension in A to be twice that in B.
Find the seepage discharge if coefficient of permiaability is 2 x 10-5 m/s.
Describe the problem of lack of coordination between design and construction in a traditional contract.In agency CM,what expertise does the CM provide during the pre-design and design phase?
What is the advantage of using a visible-beam laser instrument rather than an infrared beam laser instrument (electronic level) on a construction site?
Distance between concrete columns in 5 story building and if there is distance 15 feet than what should be the column size and how many bars and diameter of each bar?
Assume that bonding atoms touch one another, that the angle between adjacent bonds is 109.5, and that each atom internal to the unit cell is positioned a/4 of the distance away from the two nearest cell faces.
A student counted 92,90,92,91,93, and 91 paces in six trials of walking along a course of 200 ft known length on level ground. Then 85,86,86 and 84 paces were counted in walking four repititions of an unknown distance AB.
Assume that the solar energy is incident on the pond at a rate of 500 W per m2 of pond area at noontime, and that the pond is capable of storing 15 percent of the incident solar energy in the storage zone.
A rectangular plata 5 ft by 4 ft is at an angle of 30 degrees with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is 1 ft below the w..
