Example 2 Suppose one truck is parked on a bridge as shown in the Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per feet, which is uniformly distributed. We can assume the bridge is rigid. We want to know what will be the reaction forces at the supports of bridge at the two ends 1000 lbe 200 Ib/ft 25 Force? 50 Force? Figure 1
12) A 1700kg car is pulling a 3000 kg trailer over a bridge. The bridge is uniform in density and has mass 5500 kg. The only two supports on the bridge are the two pillars shown. The bridge is at static equilibrium. Call the two forces F and FR for the left and right pillars respectively. Respect standard sign conventions (as mentioned at the beginning of the exam). a) Using a rotational equation with the axis of rotation at the...
a uniform bridge span weighs 50x10^3 and is 40m long. A car weighing 15X10^3 is parked with its center of gravity located 12m from the right pier. what upward support force does the left pier provide? im lost....this is what i think im supposed to do 40m-12m= 28m to left pier 50.0x10^3- (40m/28m)*15.0x10^3= 28.5x10^3? is this right if not what am i doing wrong please help!
Two pylons hold up a 67.000 kg bridge that is 30 m long. Pylon A is 8 m from one end of the bridge and pylon B is 12 m from the other end. A 2000 kg dump truck is the middle of the bridge and a 800 kg car is 5 m from pylon A, towards the middle of the bridge. Draw an extended free body diagram and label all of the forces.
One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts...
b. find the force exerted on the bridge by the right habd
pillar.
please explain concepts and procedure step by step. thank
you

4. Two vertical ropes support a 20.0 ft long bar. Each rope is inset 5.00 ft from the ends of the bar. The bar is uniform and weighs 50.0 lb. A weight of unknown size hangs from the left end of the bar, and a 100 lb weight hangs from the right end of the bar. If the tension in the left-side rope is 80.0 lb, find both the weight of the left-side hanging weight and the tension in the...
A car (m = 1250 kg) is sitting at rest when it is hit by a truck (m = 2500 kg). After the collision, the car and truck stick together and move off with a combined speed of 6.50 m/s. How fast was the truck going when it hit the car? 9.75 m/s 19.5 m/s 6.50 m/s 13.0 m/s A long uniform rod is mounted so that it rotates around an axis through one of its ends The rod has...
2. In a head-on collision between a truck (object #1) and a car (object #2), as difficult as it is to believe, the force of the truck on the car is equal (and opposite in direction) to the force of the car on the truck. However, because of their different masses, the two vehicles have very different subsequent motion: the truck basically keeps going, while the car will get smashed up and stick to the front of the truck. Another...
