II. A two-armed sprinkler has four holes with diameter d in each arm as shown in the figure below. Water with density p flows at flowrate 8Q up through the central hub and then exits each of the 8 holes equally. The holes are designed such that the jets exit at a 45 angle as shown so that the sprinkler arms spin. hole diameter-d 459 A. The friction in the bearing limits the angular rotation rate.

Problem 1 Two identical pucks, each of inertia m, are connected to a rod of length 2r and negligible inertia that is pivoted about its center (that is, there is some sort of pin though its center, around which it can rotate without friction). A third puck of inertia m/2 strikes one of the connected pucks perpendicular to the rod with a speed vi. Assume the collision is elastic. (a) Draw a diagram of the situation, clearly labeling the direction...

A windmill has three blades that can extend or retract depending on the wind speed. Each blade can be approximated by a rod with a mass of 270 kg that is fixed at one end. The moment of inertia of each blade is 1/3 ML2, where L is the length of the blade. Each blade is 9.0 m long. Calculate the total moment of inertia of the windmill. The wind causes the windmill to rotate with a constant speed in...

We wish to determine the moment at the shoulder that is required to perform the arm motion (shoulder abduction) depicted in Figure 3 below. This motion may be modelled with a simple, single- element linkage system as shown in the figure. The shoulder joint is represented by a simple pin support centred at O. The arm and the carried weight are represented as a rigid body consisting of a rod and a cuboid. In the rigid body model, the length...

and m1 is almost about to slip up the incline. The pulley is
“ideal” and the string supporting m2 has a length of 3.0 meters.
Each mass rotates in a horizontal circle, but with different
r-values, one of which is given. Draw a clear force diagram for
each mass, write down the appropriate force equations, and solve
them to find the tension (T) in the string, the normal force...
