1. Write down Newton's Second Law for rotational motion. 2. Describe what is torque and how the torque can be calculated if the magnitude of a force and the distance from the axis of rotation to the point where the force is applied are given. 3. Write down the equation that you will use to calculate the linear acceleration using the measured radius and angular acceleration. 4. Describe what is moment of inertia. 5. Draw a free-body diagram for the hanging mass. Apply Newton's Second Law for the hanging mass and derive the equation which will allow you to calculate tension in the string using the linear acceleration, a, mass, m, and free-fall acceleration g. 6. What is(are) the force(s) exerting the torque on the disk in the experiment?

Conduct a hypothesis test for the difference between the means of two populations with a significance level of $\alpha = .1$. $\bar{x}_1 = 10, n_1 = 25, \sigma_1^2 = 1$ $\bar{x}_2 = 13, n_2 = 25, \sigma_2^2 = 3$ $H_0: \mu_1 - \mu_2 = 0$ $H_1: \mu_1 - \mu_2 < 0$ What is the value of the test statistic $z_0$? Should $H_0$ be rejected? Yes Which of the following options is a 90% confidence interval for $\mu_1 - \mu_2$? This is a list of Z values that could be helpful for this problem. $z_{.01} = -2.33$ $z_{.025} = -1.96$ $z_{.05} = -1.65$ $z_{.1} = -1.29

For the system in the figure: a. Draw the FBD. (assumption $\theta_1 > \theta_2$). Properly draw the arrows and their direction, as well as the force value for each element. f. Obtain the EOM. Indicate the sense of forces and torques. g. Obtain the transfer function $G(s) = \frac{T(s)}{\theta_1(s)}$ h. If l = 1 m, m=1kg, k=10 N/m, tau=1 N, obtain a graph of $\theta_1$ with respect to time using using the transfer function block of simulink.
