Long Question 1 (Total 20 points) Here is a very simplistic model of a sliding door controlled by a dc motor.Motor is attached to a gear box (gear on a linear rack) which converts rotary motion from motor to a linear motion of door. The armature resistance of the motor is R, the armature inductance L=0, the motor torque and back emf constants are both K, and the rotational inertia of the motor’s armature is 0. The torque T of the motor is converted to a force F on door by the gearbox. F = T/r. The angle θ moved by the motor is converted to the position x of the door by the gear box . x = θ*rThe mass of the door is m. The friction is modelled as a damper c. Your ObjectiveFind the transfer function from the motor voltage V to the door position x. TF = Kr/(mRrr*ss + (cRrr + KK)s ) Procedure Complete the Q1 parts below

A multivariate data set on office worker productivity is to be collected involving a random sample of 200 employees. The quantitative variables of interest are hours trained (HrsTrn), client satisfaction (ClientSat), and supervisor satisfaction (SuperSat). Let denote the variable measurement for the employee. (3pts) Using notation consistent with this course, what would the dimension of the data matrix be for this situation? That is, how many rows and how many columns would there be? Also, what would the dimensions of the sample mean vector and the sample covariance matrix be for this situation? (3pts) Would you expect the covariance between and to be zero or not? What about the covariance between and ? Explain your answers in the context of this situation.
