The closed vessel contains water with an air pressure of 10 psi at the water surface. One side of the vessel contains a spout closed by a 6-inch diameter circular gate hinged along one side. Horizontal axis of the hinge is located 10 ft below the water surface. Determine the minimum torque that...
A piston having a cross-sectional area of 0.07 m^2 is located in a cylinder containing water as shown in the figure. An open u-tube manometer is connected to the cylinder as shown. For h1=60 mm and h=100 mm, what is the value of the applied force, P, acting on the piston? The weight of the...
I am an undergrad Aerospace engineering student, and I am going to start my junior year this Spring. I'm really interested in what I'm studying, but the job market for Aerospace engineers is predominantly federal. Does anyone know of, or can think of, or work for a company that is in need...
m = distance of image/distance of object so we can say that m = 4 hence
di = 4 x do (where i and o represent image and object)
Then we can plug that into the equation for focal length which is
1/di + 1/do = 1/f
and we know the f, so we can solve for 'do' to get the answer :)...
A concave mirror has a focal length of 62.4 cm.
Determine the object position for which the resulting image is upright and four times the size of the object.
What formula do I use for this question? :confused:
YUP! That's what I was thinking too. One of the equations for induced emf is E=Blv but how do I get the velocity from the gravity because i am not given a time period. It's probably something just basic...but I can't seem to grasp on it at this moment.
A 5.56m long steel beam is accidentally dropped by a construction crane from a height of 3.97m. The horizontal component of the Earth's magnetic field over the region is 28.4e-6T. Acceleration of gravity is 9.8 m/s^2.
What is the induced emf in the beam just before impact with the Earth...
