A 3-m diameter roller gate retains water on both sides of a dam crest as shown below. Axes (x,y) are given in the diagram to indicate the convention for positive values. The origin of your coordinate system (O) is at the base of the roller gate where it contacts the dam. Indicate direction of Forces either with an arrow, writing the direction (ie. Right/left or up/down) or +/- sign indicating what way is positive based on the axes definition given....
Question 1 (20 marks) (a) (10 marks) This is a section of a dam that holds up water up to a height of 25 m in the spring. When summer arrives, due to evaporation, this height drops by 10 m. As a design engineer on this project, you are to design a gate for releasing water. This gate opens about a single pivot point (dark circle) by angle e (30 about the vertical axis. The customer requires some questions to...
Problem 2 A concrete dam has a curved surface and restrain water (p=1000kg/m3) at a depth H=2 m.

magnetic flux As shown in the figure, there are semiconductors with a cross-section of width w [m] and thickness t [m]. I [A] current is flowing in this semiconductor. However, the electron density per unit volume is N [m-3]. When a magnetic field of magnetic flux density B [T] exists in this space in the direction shown in the figure, an electromotive force is generated in the direction of the semiconductor. Find its direction and size В W
