An airplane propeller of total length L rotates around its center with angular speed W in a magnetic field that is perpendicular to the plane of rotation. Modeling the propeller as a thin, uniform bar, find the potential difference between (a) the center and either end of the propeller and (b) the two ends. (c) If the field is the earth's field of 0.50 G and the propeller turns at 220 rpm and is 2.0 m long, what is the potential difference between the middle and either end? It this large enough to be concerned about?

Standard air flows over a horizontal smooth flat plate at freestream speed U = 20 m/s. Theplate length is L = 1.5 m and its width is b = 0.8 m. The pressure gradient is zero. The boundary layer is tripped so that it is turbulent from the leading edge, the velocity profile is well represented by the 1/7-power expression. Evaluate the boundary layer thickness atthe trailing edge of the plate. Calculate wall shear stress at the trailing edge of the plate. Estimate the skin friction drag on the portion of the plate between = 0.5 and the trailingedge.

Implement a class Lock that simulates a lock with numerical buttons. Image of a touch tone phone keypad with numbers 1 to 9 and star, 0, and pound The push method simulates the push of a numeric button with value 0 to 9. The open method simulates the push of the key that causes the lock to open, provided that the right combination was entered. (For now, the configuration is hardwired as 1729. You will see in another section how to change it.) As the data representation, use an integer containing the digits that have been entered up to this point. You will need to figure out how to update that number. For example, if the user had previously pushed 1 and 7, causing input to be 17, and now pushes 9, how can you set input to 179? In the open method, return true if the lock would have been opened, false otherwise. Clicking that button resets the entered keys, whether or not the correct combination has been entered.
