 My tire that is sideslipping and rotating usually causes a yaw mark. a. True b. False a. True In a critical speed from yaw mark examination, you would measure your chord and middle ordinate after the crossover. a. True b. False a. True Conspicuity is defined as: C. The ability of an object to capture our attention. Gouge marks are good data in determining: D. Both A and C Newtons second law is expressed as F=Ma. A. True B. False A. True When, using the airborne equation, you can combine all post airborne events to the original airborne speed at takeoff, to obtain the speed of the vehicle. A. True B. False B. False The area of the eye where the image we are trying to see is focused is called the? E. None of the above Using Expert Autostats can be useful in estimating speeds from crush damage involving poles and vehicles. A. True B. False A. True Hot shock from lamp filaments usually occurs within 36-48 inches of the impact of the vehicle. A. True B. False A. True In a lamp that sustains cold shock, the filament will be discolored. A. True B. False B. False Which is the smallest scale? D. 1:40 Newton’s first law is a statement of inertia. A. True B. False A. True Impulse could be called the change in momentum. A. True B. False A. True A vehicle can leave yaw marks that are not necessarily critical speed yaw marks. A. True B. False A. True Prior to trial, the investigator should review their notes, case files, mentally organize elements and evidence. Rehearse, clear, convincing testimony. A. True B. False A. True Taking Linear Perimeter measurements of vehicles involved in a crash is useful in determining the approach angles. A. True B. False A. True Diagramming the crash scene using the zero point and reference line method is useful in calculating the angles of roadway, gouge marks for use in determining departure angles. A. True B. False A. True Scale diagram should be drawn for reconstructions involving a calculation of linear momentum. A. True B. False A. True “Tan θ” and “m” are exchangeable terms in the airborne equation formula A. True B. False A. True Underinflation is the leading cause of tire failure, and may result in excessive heat buildup, component separation or “blowout”. A. True B. False A. True Overinflation, increases stiffness, which may deteriorate ride, generate unwanted vibration, increase the chances of impact damage, and result in fast/irregular wear. A. True B. False A. True To convert the percent grade to degrees for the airborne equation: D. Take the 2nd tangent of the grade. What is Newton’s first law of motion? Every body at rest tends to remain at rest, whereas every body in motion tends to remain in motion, unless it is acted upon by an unbalanced external force. What is Newton’s second law of motion? The acceleration of any body is directly proportional to the force acting on the body, whereas it is inversely proportional to the mass of the body. What is another way to write Newton’s second law of motion? F=Ma What is Newton’s third law of motion? For every force exerted on a body by another body, there is an equal but opposite force reacting on the first body by the second Authorcrashley12802 ID364771 Card SetTHI Recon Description Updated2022-12-15T21:39:12Z Show Answers
