solve using analytical way Given a single disk system that rotates as in picture. If: m₁ = 10 kg; R₁ = 15 cm; 0, 30°, m₂ = 15 kg; R₂ = 20 cm; 0₂ = 100°, m3 = 10 kg; R3 = 10 cm; θ3= 160° dan R₂ = 12,5 cm, calculated "me" and "θe"

See image that is attached. Thank you.

An engine turns at 250 revolutions per minute and its stroke is 450 mm. Find the average pistol speed in meters per minute, and the speed of the centre of’ the crank pin in meters per minute.

Given: A shaft rotates about a fixed vertical axis at a constant rate of f, as shown below. A straight bar OA, having a length of L, is pinned to point O on the shaft, with O being on the rotation axis of the shaft. At the instant when 80, bar OA is being raised at a rate of 6 from the horizontal plane, with this rate changing at a rate of . A set of ryz coordinate axes is attached to bar OA with its origin at O. A second set of coordinate axes, XYZ, are fixed to ground. At the instant when = 0, the zyz and XYZ axes are aligned with each other. Find: For the instant when -0°, determine the angular velocity and angular acceleration of har OA. vertical shaft bearing O 8 X bar Use the following parameters in your analysis: f2=5 rad/s, é = 4 rad/s, 6-3 rad/s² and L=2 m.

I need the answer as soon as possible

The following diagram shows a piston moving in a cylinder with rod AB. Point B is rotating clockwise with an angular velocity of w. cylinder piston A connecting rod crank bearing B ResearchGate The motion of B is given by the equation r = C cos(wt) + Dsin(wt) Were r is the horizontal +vertical distance of B from O, and C, D are constants. For C=D=42mm and w = 20 rad/s. (i) Write r in the form Rcos (wt ± ß) and state the amplitude and period of r. (ii) Sketch one complete cycle of r. (iii) Explore the differences between the derived form and drawn form

Required information A model of a person's arm is used for ergonomics studies. Distances are rAB = 30 cm, BC = 28 cm, and rCD = 19 cm. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. y D C25° 30 Determine the position vector TAD and its magnitude rAD· The position vector TAD 1i)cm and the magnitude rAD is cm.

All problems will use the conventional Cartesian coordinate system unless noted otherwise. Positive x-axis points to the right, Positive y-axis points up, Angles are measured CCW (counter-clock-wise) from the positive x-axis. Problem-BB: Consider FIG-BB in the appendix. AC is a rope. BC is a rope. “C” is a steel ring. “D” is a perfect pulley. A continuous rope connects “C” to the mass.   Calculate the internal forces within each rope.
