Required information The cutaway of the gun barrel shows a projectile moving through the barrel. The projectile's exit speed is vs = 1675 m/s (relative to the barrel), the projectile's mass is 18.5 kg, the length of the barrel is L = 4.4 m, the acceleration of the projectile down the gun barrel is constant, and Ⓡ is increasing at a constant rate of 0.18 rad/s. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. L Determine the pressure force acting on the back of the projectile. It is given that = 20°. (Round the final answer to four decimal places.) The pressure force on the projectile is 31.8882 × 106 N.
A pick and Place machine is being used to transfer a box. The arm is extended (out) by energizing a solenoid valve; when the valve is de-energizes, the arm retracts (in). In the same way, a second valve closes the grip (when energized) or opens the grip (when de-energized). Here's a diagram of this "machine": Grip Air Cylinder Grip open Grip Closed Box Arm Air Cylinder Arm In Arm Out The system is really slow... it actually takes 3-4 seconds for the arm to fully extend. An engineer created the below diagram. Start Pressed Time (seconds) Box Falls - 1 -2 -3 - 4 - 5 -6 –7 -8 – 9 – 10 Extend Arm Close Grip Question (finally!). Which statement is completely true regarding this design? It uses the Master Clock scheme. Given this diagram, the arm will probably start to retract before the grip fully closes. O If the arm takes 4 seconds to retract (return), the box will be dropped "mid-flight" It uses the Domino Scheme. Things can't happen in the wrong sequence. It uses the Master Clock…

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. A basic slider-crank mechanism 0< 0< 2n; b = 20 cm; I= 50 cm 1- Find the angle of Ø and the distance of dAC as a function of 0. 2- If crank AB has a rotational speed of w = 1000 rev/min; find velocity of C (Vc) and velocity and acceleration of link BC (vBC & aBC)

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.
