Conventional float actuated device is used as a level measurement sensor, which consist of pulley and a pointer which move over a graduated scale. Let say you are asked to develop a controller-based float actuated system having a sensor for level measurement or may be more than one sensor is required for accurate level measurement, which sensor will you use and why? Draw the whole schematic showing the position of the sensor or sensors. Will pulley be part of your new digital system, if yes justify your answer, if no, then how you will develop a system without using pulley.

magnitudes F₁ A scissors truss supports three forces at joints B, C, and D as shown in the figure below. The forces have 35 kip, F₂ = 10 kip, and F3 = 25 kip. The truss is held in equilibrium by a pin at point A and a roller at point E. Note that sides ABC, CDE, AFD, and BFE are straight lines, and member CF is vertical. Joint F lies s = 12 ft to the right and h = 4 ft above joint A, and joint C lies h = 4 ft above joint F. Use the method of joints to determine the force in each member of the truss, and indicate whether they are in tension or compression. Note: Express tension forces as positive (+) and compression forces as negative (-). = A. HA B S F₁ F₂ 2 F C F3 D S E A h h

(More practice from Monday) A 90° elbow in a horizontal pipe is used to direct a flow of oil (SG = 0.87) upward at a rate of 40 kg/s. The cross- sectional diameter of the elbow is a constant 20 cm. The elbow discharges at A into a large holding tank where the level of oil is 1.8 m above A. The 50 cm "weight" of the elbow and the oil in it is 50 kg. Determine (a) the gage pressure at the inlet of the elbow and (b) the anchoring force needed to hold the elbow stationary. Take the momentum-flux correction factor to be 1.03 40 kg/s at both the inlet and the outlet. Activar Windows Ve a Configuración para activar Windows.

1) A slider-crank mechanism is a planar mechanism that performs a conversion between the translational motion of a slider and the rotational motion of a crank. It is used in many different engineering applications. A familiar example will be a piston engine. In Figure 1, a basic slider- crank mechanism is shown. В b dạc Figure 1.
