At the instant shown, link CD rotates with an angular velocity of CD= 8 rad/s. If link CD is subjected to a couple moment of M=650 lb.ft, determine the force developed in link AB and the angular acceleration of the links at this instant. Neglect the weight of the links and the platform. The crate weighs 150 lb and is fully secured on the platform.

The Laws of Physics are written for a Lagrangian system, a well-defined system which we follow around – we will refer to this as a control system (CSys). For our engineering problems we are more interested in an Eulerian system where we have a fixed control volume, CV, (like a pipe or a room) and matter can flow into or out of the CV. We previously derived the material or substantial derivative which is the differential transformation for properties which are functions of x,y,z, t. We now introduce the Reynold’s Transport Theorem (RTT) which gives the transformation for a macroscopic finite size CV. At any instant in time the material inside a control volume can be identified as a control System and we could then follow this System as it leaves the control volume and flows along streamlines by a Lagrangian analysis. RTT:DBsys/Dt = ∂/∂t ʃCV (ρb dVol) + ʃCS ρbV•n dA; uses the RTT to apply the laws for conservation of mass, momentum (Newton's Law), and energy (1st Law of…
Fluid Mechanics: Concept Question: From Bernoullis equation, if you have point A and point B, where point A is at a higher elevation than point B, lets say Z1 and Z2 respectively - You have a pump running the fluid from point B to point A , i.e. against gravity. I understand the following: Pressure losses, h, moves in the same direction as your flow, v, and your friction, f, moves opposite to your flow, always. So the head loss AS A RESULT OF FRICTION from Z2 to Z1, will be negative or positive? I assume negative, and the value of the aforementioned head loss will be positive in the bernoulli equation on the side of the equation involving A , as this is the direction the flow is moving towards. Hence my question: So the head loss AS A RESULT OF FRICTION from Z2 to Z1, will be negative or positive?
In a nutshell, a smaller rock is propelled into the air as a huge counterweight in the back falls down, effectively converting gravitational potential energy into kinetic energy for the rock and the weight. But, since the rock is smaller.. it is propelled at a much faster velocity! Let's say we wanted to hurl a 50 kg boulder at a castle wall 100 meters away. Our wooden structure for the trebuchet is 10 meters tall, so that is the maximum distance the counterweight can fall. Assuming the launch angle is a perfect 45 degrees, and the boulder is released from ground level, derive the needed mass of the counterweight that will give the boulder enough kinetic energy to reach the base of the castle walls. You may assume no energy is "lost" due to friction, and ALL the counterweight's gravitational potential energy is converted into the boulder's kinetic enerqy. (HINT: You will need to employ 2D kinematics to find the needed final velocity, then use that final velocity in an energy equation…
