Let's dive into a couple of master-level Motion Analysis questions, along with comprehensive solutions prepared by our experts:
Question 1: Motion Analysis of a Mechanical Linkage
Consider a four-bar linkage mechanism where links AB, BC, CD, and DA are connected in a loop. Link AB is driven by a motor that rotates at a constant speed of 120 RPM clockwise. Link AB has a length of 0.5 meters, while links BC, CD, and DA have lengths of 0.3 meters, 0.4 meters, and 0.6 meters respectively. Determine the angular velocities and accelerations of links BC and CD when link AB is at an angle of 30 degrees from the horizontal.
Solution:
To solve this problem, we will use the principles of kinematics and dynamics. Let's denote the angular velocity of link AB as ω_AB. Since the motor rotates at 120 RPM, ω_AB = (120 RPM) × (2π rad/rev) / 60 = 4π rad/s.
The angular velocity (ω_BC) and angular acceleration (α_BC) of link BC can be determined using the following equations:
ω_BC = ω_AB × (Length of AB / Length of BC) × sin(θ) α_BC = α_AB × (Length of AB / Length of BC) × cos(θ) - ω_AB² × (Length of AB / Length of BC) × sin(θ)
Substituting the given values: ω_BC = 4π × (0.5 / 0.3) × sin(30°) ≈ 13.09 rad/s α_BC = 0 (since ω_AB is constant)
Similarly, we can calculate ω_CD and α_CD using similar equations.
Question 2: Dynamics of a Pendulum
A pendulum consists of a rigid rod of length 1.5 meters attached to a pivot at one end. At the other end of the rod, there's a mass of 2 kg. If the pendulum is released from an initial angle of 30 degrees with the vertical, calculate the tension in the rod when the pendulum reaches the lowest point of its swing.
Solution:
To find the tension in the rod, we need to analyze the forces acting on the pendulum. At the lowest point of the swing, the tension in the rod (T) will be equal to the centripetal force required to keep the mass moving in a circular path.
Using the principle of conservation of energy and considering the forces involved: T - mg cos(30°) = m(v² / L) where, T = tension in the rod, m = mass of the pendulum, g = acceleration due to gravity, L = length of the pendulum, v = velocity of the mass at the lowest point.
Substituting the values: T - (2 kg × 9.8 m/s² × cos(30°)) = 2 kg × (v² / 1.5 m)
By solving for v and subsequently for T, we can find the tension in the rod when the pendulum reaches the lowest point of its swing.
