Drop-load (I)This exercise is part of a series of problems aimed at modeling a situation by progressively refining our model to take into account more and more parameters. This progressive approach is very close to what professional scientists do! context We want to lower a suspended load in a controlled way, so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on a horizontal surface. To slow down the descent, we added a spring behind the mass (A).   Information The masses of the charges A and B are known.The mass of the rope itself is negligible (very small compared to the loads).The pulley has negligible mass and can rotate without friction.The charge ? is initially stationary and is at a known height h.The surface on which mass A is placed is horizontal.There is no friction between mass A and the surface on which it is placed.The string attached…

Fluid mechanics [Rotation and Translation of Fluid Masses] An rectangular tank with a width of 1.5 m, a length of 3.0 m, and a height of 2.0 m is filled with a liquid (sg = 0.8) to a depth of 1.5 m. The tank is accelerated along its length by a magnitude of 2.5 m/s2. Determine the forces acting on (a) the leading side of the tank, and (b) the rear end of the tank. Find the:a. lead side =__________kN b. rear side =__________kN

A physics lab consists of a large ball attached to a wire. Students hold on to one end of the wire, then whirl the ball around in circles and count the number of rotations per second. One group finds these numbers: ball mass= 320 gram, wire length= 1.3m, number of rotations/sec=2.5. The wire is made of steel with a diameter of 1mm and a Young's modulus of 20x10^10 N/m^2.How much does the wire stretch due to the tension on it? Should the students correct their data for the wire stretching?

We consider a bar rotating, with friction due to viscosity, around a point where a torque is applied. The non-linear dynamic equation of the system is given by ml²ö = -mgl sin 0 – kl²ė + C where 8 - is the angle between the bar and the vertical axis; C- is the torque (C>0); k – is a viscous friction constant; l- is the length of the bar; m – is the mass of the bar; a) Choose appropriate state variables and write down the state equations; b) Find all equilibria of the system, assuming that < 1; c) Linearize the system around equilibrium points and determine the eigenvalues for each equlibria; mgl
