Now our robotics team is trying to tighten one of the ¼" - 20 UNC bolts to hold on the wheels. They are using a wrench that is 6" long. They exert 10 lbs to pull the wheel toward its axle with 110 lbs of force. Fill in the values for this situation: how do i know what the Fe is in the scond sentence?
A rigid bar of mass m and length L is released from rest in the horizontal position. What is the rod's angular velocity when it has rotated through 90°?
A body moves through standard air at 200 m/s. What is the stagnation pressure on the body? Assume (a) compressible flow and (b) incompressible flow.
Solve for the pressure of a gas using both equations at a temperature of 400K and a molar volume of 1x 10-4 m3/mol. For the van der Waals EOS, use parameters of a= 4.1x10-1 (m3/mol)2 Pa, and b=4.3x10-5 m3/mol.
Determine (a) the exit temperature, (b) the exit relative humidity of the air, (c) the exit velocity.
this is concerned a little more into aerodynamics, what are the uses of wind tunnels including the importance of geometric and dynamic similarity and wind tunnel interference?
Determine the resulting stress equations for σx, σy and τxy given the Airy's stress function ? = a1x^4 + a2(x^3)y + a3(x^2)(y^2) + a4x(y^3) + a5(y^4), where ai are constants. Also determine, if any, the restrictions between constants.
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
Need help with determining the rate of heat generation required at the welding source to accomplish a weld. A fillet weld is used to join two medium carbon steel plates each having a thickness of 5.0mm.
the suspended load exerts a force F=600 lb at A, and the weight of the bar OA is negligible. Determine the tensions at the cables and the reactions at the ball and socket support O
where k is the coefficient of kinetic friction between the blocks and the ground. Also, what is the distance the blocks slide on the surface before they separate?
Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.
Water enters a 2 meter diameter pipe at a temperature of 23 deg C. The water leaves the pipe at a temperature of 97 deg C The laminar flow rate is such that the Reynolds number is 800. What is the mass flow rate?
