Today, we delve into two master-level questions that challenge students in the realm of SolidWorks motion analysis. Our expert has meticulously crafted solutions to these problems, providing insights that will aid both learners and professionals alike in understanding complex motion scenarios.

Question 1: Planar Pendulum Motion

Problem Statement: A planar pendulum consists of a rigid rod of length 1 meter with a point mass of 2 kg attached at its end. The rod is pivoted at one end and swings freely under gravity. The initial conditions are as follows:

• Initial angle with the vertical: θ0=30∘\theta_0 = 30^\circθ0​=30∘
• Initial angular velocity: ω0=0\omega_0 = 0ω0​=0

Calculate the following:

1. The angular acceleration of the pendulum.
2. The angular displacement as a function of time.
3. The angular velocity after 2 seconds.
4. The maximum angular displacement during the motion.

Solution Approach: To solve this problem using SolidWorks motion analysis, follow these steps:

1. Define the Assembly: Model the pendulum assembly with the rod and point mass in SolidWorks.
2. Set Up the Motion Study: Create a motion study and define gravity as the external force acting on the pendulum.
3. Apply Initial Conditions: Input the initial angle θ0\theta_0θ0​ and angular velocity ω0\omega_0ω0​ in the motion study settings.
4. Run the Analysis: Execute the motion analysis to obtain time-dependent angular displacement, velocity, and acceleration.
5. Analyze the Results: Extract the required parameters such as angular acceleration, displacement as a function of time, velocity at specific instances, and maximum displacement.

Question 2: Cam and Follower Mechanism

Problem Statement: Design a cam and follower mechanism where the follower moves with a specified motion profile. The cam must be designed such that the follower moves with the following displacement function: y(t)=0.05t3−0.1t2+0.02t+0.1y(t) = 0.05t^3 - 0.1t^2 + 0.02t + 0.1y(t)=0.05t3−0.1t2+0.02t+0.1 The motion is constrained between $t=0$ and $t=5$ seconds. The cam rotates at a constant speed of 10 radians per second. Determine:

1. The cam profile equation in terms of its radius $r(\theta )$.
2. The angular velocity of the cam.
3. The angular acceleration of the cam.

Solution Approach: To model this cam and follower system in SolidWorks:

1. Create the Cam Profile: Define the cam profile equation $r(\theta )$ that ensures the follower moves according to the specified displacement function.
2. Implement Motion Constraints: Set up the motion study with the cam rotating at a constant speed.
3. Analyze Angular Velocity and Acceleration: Use SolidWorks to compute the angular velocity and acceleration of the cam as it rotates.

By following these steps, you can accurately simulate and analyze complex motion systems using SolidWorks motion analysis capabilities. These tools not only help in solving theoretical problems but also enable engineers to visualize and optimize real-world mechanisms efficiently.
