Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

3. In a science fiction story about space exploration an expedition to Mars was
described. The space ship landed in a rocky valley and the astronauts promptly
prepared their vehicle for a trip on the planet's surface. This special vehicle was
designed with big inflated tires. On the very first steep slope the vehicle tipped
over. They did have small steel balls onboard to increase traction. They thought
of suspending a bunch of them beneath the vehicle to lower its center of gravity,
but that would decrease the clearance and cause the weights to strike rocks and
the ground more often
How could it be done?

Expert Solution

Step 1: Introduction

In physics, a centre of gravity is an imaginary place in a body of matter where the whole weight of the body may be believed to be concentrated for ease in certain computations. In a homogeneous gravitational field, the centre of gravity is the same as the centre of mass, as physicists prefer to call it.

The centre of gravity is defined as the point in a system or body where the weight is uniformly distributed and all sides are balanced. The centre of a seesaw is an example of a centre of gravity.

Look at the following arrangement. Block A is held at rest on the frictionless wedge B by a massless rope that passes over a massless and frictionless pulley attached to the ceiling. The wedge sits on a scale. The wedge is not anchored in any way to the scale, and it is initially held at rest by a hand in such a way that the rope on the left of the pulley is oriented vertically. a) What is the scale reading after letting go of the wedge gently until the wedge comes to rest? b) What is the orientation of the rope after letting go of the wedge gently until the wedge comes to rest?

If the mass of the hanging-mass is increased and the mass of the cart remains the same, how would the steepness of the position versus t2 be affected? The best-fit line would decrease in steepness.The best-fit line would increase in steepness. Impossible to determine because the net force is not a part of the position vs t2 graph.There would be no change in steepness.

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.
