Problem 6-72

Determine the resultant force at pins A, B, and C on the three-member frame.

Step-by-Step Solution:
Step 1 of 3

CS 1110 Van Loan and Lee Spring 2016 April 5, 2016  Dictionaries o an item has a key and a value  values are assigned to keys o set up  use a colon to separate a key from its value  separate items with a comma  enclose the whole thing with {} o dictname.keys()  list of keys o dictname.values()  list of the values o delete a dictionary item  del dictname[‘keyname’] o checking if a dict has a particular key  Boolean  ‘keyname’ in dictname o extracting a value  keys are like subscripts  variablename = dictname[‘keyname’] o adding an item to a dictionary  dictname[‘nameofkeynotindict’]=value  items in a dictionary are randomly ordered  if the named key already exists then the value of that key is changed o list vs. dictionary  dict: keys mapped to values  list: integers (indices) mapped to values o copying dictionaries  copy = dict(originaldict) o use loops to go through dictionaries o keys must be strings or numbers, values can be anything  all values in a dictionary do not have to have the same type April 7, 2016  Objects and Classes o classes: packages data into units  defining the point class  build the point given info (using the constructor method) o builds a point object  to define a point, you need to define a new type  define the attributes of the class  __init__ (double underscore function) o initializing, method to write a constructor o “def __init__(self,x,y):” o always start with self  the first argument when writing a constructor o under the __init__, assign incoming values to self’s attributes o object  holds and organizes data  attributes are variables that live in the object  use dot notation to access and manipulate attributes  pretty printing (define a __str__ method in the class)  note: whenever you have a method that is defined in a class in the same module, the first argument is always self  method thinking  apply the method to a pair of certain objects
