ements Constants ents SOLUTION We will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis. As shown in (Figure 1), a car engine with weight to hangs from a chain that is linked at point to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that is given and...
In figure Q3 a car engine with weight w hangs from a chain that is linked at point O to two other chains, one fastened to the ceiling and the other to the wall. (i) Draw the free body diagram for the engine. (ii) Given the value of weight w is 2200N, find the tension in T1, T2 and T3 Chapter force and motion 3. In Figure Q3 a car engine with weight w hangs from a chain that is...
this example shows the uses of co-coordinate axes, my question is why is it that we can substitute T for w2 for the second equation , won t it be wrong since we are using two different sets of axes does it have something to do with expressing newtons second law in terms of magnittude? can someone explain more about the uses of co-coordinate axes and when is it not apprioriate not to use it? 5.2 Using Newton's Second Law:...

Dr. C. #2. (PHYS 121 engineering design exercise) You have seen why cars inherently accelerate quicker in a straight line and have better fuel mileage than an SUV with the same engine; it's because of air drag and the smaller frontal area and better drag coefficient of the car. Now let's think about why cars handle (take turns, change lanes and make other quick maneuvers) better than an SUV. We'l1 simplify our analysis by considering a vehicle of mass M...
