QUESTION 4 for Gradescope: Consider the region shown below (a triangle with a quarter circle).  If the density is  δ ( x ) = 3 + x 2  grams/cm 2 {“version”:”1.1″,”math”:”\delta(x)=3+x^2 \text{ grams/cm}^2″}set up an integral to find the total mass of the region. (The x- and y-axes in the picture are measured in centimeters, and the variable x in the density function is the x-coordinate of a point on the shaded region shown.) Show all supporting work. In particular, include a sketch of a representative slice labeled with dimensions needed to calculate the mass of the slice, and show all intermediate steps. You do NOT need to evaluate the integral.

Using the function template below, type a working recursive function.  Make sure your function conforms to the instructions given in the comments for the function.    

Beam ABCD is supported by two cables at points E and F and has a smooth support at D. The beam is subjected to a distributed load, a point load and a couple moment at point C, as shown in the figure. Determine the reactions at each support. Note that a Free Body Diagram (FBD) is required to receive full points.

The structure is supported by a journal bearing at point A and a cable at point B. Which of the following is the correct Free Body Diagram?

The bracket ABC can be supported in the four different ways shown. All connections consist of smooth pins. Circle the case which is improperly constrained. Justify your selection.

Mr. White has been diagnosed with a 4.2 cm abdominal aortic aneurysm. The nurse is providing education to the patient about the aneurysm. Which of the following teaching points is the most appropriate point for the nurse to reinforce?

Give the definition of the removeFront function. This function removes a node from the front of a Deque object, and returns the value that was stored in the removed node. You can assume the calling object is not empty before a removeFront function call.

Using the function template below, type a working recursive function.  Make sure your function conforms to the instructions given in the comments for the function.
