The rigid L-shaped member ABC is supported by a ball and socket at A and by three cables. Determine the tension in each cable and the reaction at A caused by the 242 kg load applied at G.
Geometric angle of attack, The Piper Cherokee has a wing area of 170 ft2 and a wing span of 32 ft. Its maximum gross weight is 2450 lbs. The wing uses a NACA 65-415 airfoil, which has a lift slope of 0.10331deg^-1 and alpha(L=0)= -3.0deg. Assume th..
In the gear-and-shaft system shown, the shaft diameters are dab= 2 in. and dcd=1.5 in. Knowing that G = 11.2 x10^6 psi, determine the angle through which end d of shaft cd rotates.
a 13.2-N force P is applied to the lever which controls the auger of a snowblower. Determine the moment of P about A when alpha is equal to 30 degrees.
you are given a task of compressing a fixed quantity of gas from P1,T1 to P2,T1. you wish to do this using a polytropic process coupled with a constant pressure P2 heat-transfer process. determine the polytropic process that minimizes the entropy ..
Employing the ideal gas model, determine the change in specific entropy between the indicated states, in Btu/lbmol?ºR. Solve 2 ways: Use the appropriate ideal gas table AND also by using a constant specific heat value.
At a given instant in time, flywheel OA is caused to rotate with angular velocity of w=2rad/sec and angular acceleration of alpha=6rad/s2. determine the angular velocity of links AB and BC at this instant in time. AB=.5m, BC=.4m, OA=.3m
(a) Draw a schematic of the system and (b) determine if the inventor's claims are true.
Motor coming to rest, A motor is running at 12 rpm and the switch is flipped and cuts the power. The rotor weighs 75 lbs.
Determine Fourier Number, Compare two identical steel spheres, except the first has a two inch diameter while the second sphere has a four inch diameter. The larger sphere will have a Fourier number approximately
Why do thermoplastics tend to become brittle in very cold weather?
If the bar is subjected to centric forces of magnitude P = 30 kN and knowing that EA = 70 GPa and EB = 105 GPa, determine the normal stress (a) in the aluminum layers, (b) in the brass layer.
