Concept explainers

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.

Part C

Review
Learning Goal:
the pulley is massless
Express your answer to three significant figures and include the appropriate units.
To draw the free-body diagram of a point particle, use the equations of
equilibrium to find unknown forces, and understand how frictionless
pulleys affect the transfer of force in a cable.

As shown, a mass is suspended from a cable that wraps around a
frictionless and massless pulley. The cable connects to a linear elastic
spring. For this problem, treat the pulley as a point particle at B.

v Correct
Correct answer is shown. Your answer 1813.5 N was either rounded differently or used a different number of significant figures than required for this part.
Part B showed that the weight of the hanging mass is equal to the force on the spring, W = F,. This answer is expected from your instructions on pulleys. It
should have been made clear that frictionless pulleys will only redirect a force. The proof of this will be learned at a later time.

Select all true statements. ANFO explosive is often preferred because using bulk explosives is cheaper, less labor intensive during loading and they fill the entire blast hole diameter. Emulsion explosives should not be used in strong and massive rocks where a high detonation pressure and high detonation velocity is required to break the rock. During rock fragmentation by blasting, the reflection of the compression wave at the free face into tension and shear waves contributes to additional cracking between the free face and the blast hole. When metals or other reactive elements are present in the composition of an explosive, less oxygen is required for a an oxygen-balanced reaction.
