- Only do parts D and E please. A carousel with a radius of R = 3.0 meters is initially at rest. It is then given a constant angular acceleration ? = 0.6 rad/s2 . A. Sketch the physical situation and label your sketch with appropriate quantities from the problem statement. Make a table of known/given information and unknown/wanted information (this may involve reading the rest of the problem before starting). List any physical assumptions you will be making to solve the problem. B. What is the angular velocity of the carousel after t = 8 s? What is the linear velocity of a child located at 2.5 meters from the center of the carousel after t = 8.0 s? What is the tangential acceleration of the child at that time? What is the child’s radial acceleration at that time? C. Determine the magnitude and direction of the child’s total acceleration vector after 8 seconds. Add this vector to your diagram above and show the directions of the radial and tangential components. D. How many rotations…The subject is all about dynamics. The topic is all about the Curvilinear Motion of Particles or Tangential and Normal Components. Please use two decimal places and show the conversion process. Use pen and paper to solve. Thank you. Here are the formulas: a_x=0 a_y=-g v_x=v_xo v_y=v_yo-gt x=x_o+v_xo t y=y_o+v_yo t-1/2 gt^2 for the Tangential and Normal Components fomulas: a_t=dv/dt a_n=v^2/ρA. Determine the sum of moments about point A of the system of forces shown in the figure. Each square is one meter on a side. Find the resultant couple (moment) at point B. For computation, use the slope for slant forces.
- Make a sketch of the problem situation similar to the one in the Equipment section. Indicate the path taken by the rubber stopper. In this case you may want to make two pictures: a top view and a side view. Label the length of the string between the top of the cylinder and the rotating stopper, the mass of the rubber stopper and hanging washer(s), and the velocity and acceleration vectors of the stopper. Because gravity pulls downward on the stopper, the string slopes slightly downward in the picture. For simplicity, in this problem you can assume the string is approximately parallel to the ground. Draw a new side view picture with the stopper moving purely horizontally. Draw separate free-body diagrams of the forces on the stopper and the forces on the hanging washer(s) while the stopper is moving horizontally. What assumptions, if any, are you making? Assign symbols to all of the forces, and define what they represent next to your diagrams. For easy reference, it is useful to…The strongback or lifting beam is used for materials handling. The suspended load has a weight of 2 kN and a center of gravity of G. The lifting bridle has two legs that are positioned at 45°, as shown in (Figure 1). Suppose that a = 0.22 m. Figure 1 of 1 3 m 3 m d 45° 456This is the answer to one of my practice problems, however I don't understand how the angular acceleration is simplified for A, B and C. How does rFsin90/(2M)(2L) equal 3F/ML and etc. for the other ones? And then after you simplify all the angular accelerations, how do you know which one is smallest to greatest? How do you tell that C is greater than B?
