In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw. Guide A starts from rest with pin P at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 110 mm/s at the halfway point of its vertical displacement. The guide then decelerates at a constant rate and comes to a stop with pin Pat the uppermost point in the circular slot. Determine the n-and t-components of acceleration of pin Ponce the pin has traveled 20° around the slot from the starting position. 22% Answers: an 285 mm i mm/s² mm/s²

In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw. Guide A starts from rest with pin P at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 130 mm/s at the halfway point of its vertical displacement. The guide then decelerates at a constant rate and comes to a stop with pin P at the uppermost point in the circular slot. Determine the n- and t-components of acceleration of pin P once the pin has traveled 29° around the slot from the starting position. Please solve step by step

It is known that the static frictional force between block B and the plate will be overcome and the block will slide when its acceleration reaches 3 m / s2 (Figure 7b_4). If the plate starts from rest at t = 0 s and accelerates uniformly at a rate of 4 rad / s2 , determine the time t and the angular speed of the plate when the block starts to slip (r = 200 mm).
The conveyor belt shown below is inclined at an angle of 25 degrees. A 3kg package B is placed on the conveyor belt at the position shown with an initial velocity of 0 m/s with respect to the ground. The belt is moving quite fast, and as one could imagine the package is initially slipping, but it's accelerating at a rate of 3.05 m/s^2 until it catches up to the velocity of the belt. If this is the case, find the coefficient of friction between the belt and the package.
The rotation of an element in a mechanism is managed so that the rate of change of angularvelocity with respect to the angular displacement is a constant - λ. If the angular velocity of theelement is ωo at the start when θ = 0 and t = 0, derive the expression for angular displacement,angular velocity and angular acceleration as functions of time.
