3. (0.2 pts) Arrange the gametes from mother and father (problem 2) into a Punnett square format (hint 1: only need a |*1 Punnett Square (not a 2 * 2 ). ( Hint 2: You should notice that the genotype results in a phenotype of all kittens having black fur and curled ears .)

3. Two polymer blocks shown in figure are bonded to a rigid support mount and to a movable plate (1). The polymer block has a Young's modulus E=10 GPa and Poisson's ratio 0.45. When a force P = 1,600 N is applied to the assembly, determine the horizontal deflection of plate (1).

4. Make function machines with 4 input and 4 output values using the given rules below: a. Subtract 10 from the input value b. Multiply the input by 3 c. Multiply the input by 2 and then add 5 d. Add 5 to the input and then multiply by 2 e. Are the output values for question (c) and (d) the same? f. Does it make a difference whether we first add and then multiply or first multiply and 5. Find the rule for calculating the output value for every given input value in th

Experimental Work Build a SIMULINK® model of the speed control system given in Figure 2-4 with k_a = 12 mV/(rad/sec), $T_m = 2.5$ sec, $a_m = 10$ (rad/sec)/V. In the amplifier gain block, enter -something like- "k_a". Use a step reference speed of 100 rad/sec and a step disturbance input of 10 rad/sec, which is applied 5 seconds later than the reference step. Add scopes to properly visualize the simulation results. Also use "To Workspace" blocks to send the time (generated by "Clock") and the shaft speed signals to the workspace. Write a MATLAB® m-file that defines "k_a" and then simulates the speed control system model that you have built above. Simulate the model and collect the time and shaft speed for three different choices of "k_a": k_a = 10, k_a = 20, k_a = 50 Collect and plot the shaft speed signal versus time for these three different cases all in the same figure. Use appropriate plot types, colors, labels and legends to identify the curves clearly. Adjust the time range, if necessary, to display the variations of the speed in a visible form.
