In summer, the outer surface of a glass filled with iced water frequently "sweats." How can you explain this sweating?
Initially the air in this tank is at 20 psia and 70 degrees F. Presuming that the ank is well insulated determine the temperature and mass in the tank when it is filled to 120 psia.
a tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. what measurements should be laid out to establish a horizontal distance of 682.25ft
For an intermediate beam in 3 bays by 3 bays (each bay is 20' by 20') floor plan, draw the envelope shear and moment diagrams taking into account effect of pattern loading.
Two boards each having the same EI and length L are crossed perpendicular to each other as shown. Determine the vertical reactions at the supports. Assume the boards just touch each other before the load P is applied.
At the instant shown, car A has a speed of 20 km/h, which is being increased at the rate of 300 km/h2 as the car enters an expressway. At the same instant, car B is decelerating at 250 km/h^2
Matt is building a stand made out of mud bricks ( ultimatecompressive strength approximately 100 psi and density 250lbs/cubit foot) in the shape of a tent (triangular sides, verticalfront and back).
