Question

In the movie Jurassic Park, there is a scene in which some members of the visiting group are trapped in the kitchen with dinosaurs outside. The paleontologist is pressing against the center of the door, trying to keep out the dinosaurs on the other side. The botanist throws herself against the door at the edge near the hinge. A pivotal point in the film is that she cannot reach a gun on the floor because she is trying to hold the door closed. If the paleontologist is pressing at the center of the door, and the botanist is pressing at the edge about 6 cm from the hinge, estimate how far the paleontologist would have to relocate in order to have a greater effect on keeping the door closed than both of them pushing together have in their original positions.

Explanation / Answer

for suppose say that they push the door with same force

but we have that the torque is " T "

T = force X distance

T = F X d

then the torques are the F X 6 and F X 0.5 w

T = F X 6 + F X 0.5 w

wis the width of the door

then can finally say that paleontologist pushing the near center of door it shifts far from the hinges by 6 cm

and botanist can retrieve gun by confident the paleontologist is provides the torque that they two of them..
