At a temperature of 9°C, a 2-mm gap exists between two polymer bars and a rigid support. Bars (1) and (2) have coefficients of thermal expansion of t1 = 102 x 10-6 /°C and t2 = 66 x 10-6/°C, respectively. The supports at A and C are rigid. Determine the lowest temperature at which the 2-mm gap is closed.
Given simply supported beam with an overhang. The beam is 12 inches wide by 24 inches deep, and the slab is 6 inches deep. use a roof live load of 20 psf, and a concrete density of 150 pdf. the beams are spaced 15 feet apart.
A ballon is tethered at a height of 16.8 m above the ground by three cables. if the tension in highlighted cable is 60 N , determine the vertical force exerted by the balloon at the base of the balloon basket.
Determine the required thickness of the pipe wall if the operational pressure head (pressure head in the pipe under regular flow conditions) is 40 m and if the flow control valve on the downstream end closes suddenly, developing a water hammer in ..
The crate has a wieght of W = 350lb., and the coefficients of static and kinetic friction are us = 0.3 and uk = 0, respectively. Determine the friction force on the floor. Theta = 45 degrees and P = 100lb.
hydrogen is flowing in a 50 mm diameter pipe at a mass rate of 0.01 kg/s. at section 1 the pressure is 280 kPa abs and t= 25 . what is the average velocity?
My question is regarding UVA levels in raw and treated drinking water with regard to TOC and DOC removal. Is there a jar test procedure that incorporates the UVA values of the various stages of treatment and is there a document you could refer me ..
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
The cables A and B exert forces FA and FB on the hook. The magnitude of FA is 100 lb. The tension in cable B has been adjusted so that the resultant of the two forces is oriented perpendicular to the wall to which the hook is attached.
For some minerals color is a diagnostic property making identification rather easy. However, certain minerals can also occur in a wide variety of colors making color a poor tool for identification. List different colors for the mineral quartz lo..
Design the ramp for the highest design speed (to the nearest 5 mph) without exceeding a minimum D of 8.0. (Assume the PC of the horizontal curve is at station 15+00, and the vertical curve PVIs are at the PC and PT of the horizontal curve). Maximu..
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much.
A simple supported beam 6m long is composed of two C200x28 channel RIVETED FRONT TO FRONT . What uniformly distributed load can be carried in addition to the weight of the beam w/o exceeding a flexural stress of 125MN/m^2
