L? ?? 40mm F L? 30mm ?? 30mm R 3. A mechanical sliding mechanism is designed for two arms to move the roller at point C along the ground. A force F = 100 N is applied at the connecting link. The long arm OA has length $l_1 = 50 \text{ mm}$ and the short arm has length $l_2 = 42.43 \text{ mm}$. A restoring force, R, is applied to prevent the system from accelerating a. What angle, $\theta_1$, would the restoring force be R = 0? b. When the system is in the given configuration above, what is the restoring force R?

Step 1

To find the angle θ, we can use the cosine rule. The cosine rule states that for any triangle with sides a, b, and c, and angle θ opposite to side c, the following equation holds: c^2 = a^2 + b^2 - 2ab*cos(θ) In this case, side a is the length of the long arm Show more…
