6-lug wheels are measured like 4-lug wheels. Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.. Note: When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured using a bolt pattern gauge. A bolt pattern gauge is a specialty tool and is not widely available.
Palpation should be done using the fingertips and intensity of the pulse graded on a scale of 0 to 4 +:0 indicating no palpable pulse; 1 + indicating a faint, but detectable pulse; 2 + suggesting a slightly more diminished pulse than normal; 3 + is a normal pulse; and 4 + indicating a bounding pulse.
Best Answer: The grade refers to the intensity or loudness of the murmur. Grade 1 is barely audible so grade 2 would be slightly louder. Systolic refers to the heart compressing (beating) to pump blood out of the heart. That must be when the murmur is present. It is likely that the defect is causing the murmur.
