Question

Draw the free-body diagram for 30° 15* m - 600 kg Problem #2 (5 points) Which of the following best describes Conditions for Equiliberium a When the components of the force system produce a resultant h. When the force systen acting on a body produces a resultant c When the resultant of the force system acting on body is zero, it's in equilibrium d. When the resultant of the force system acting on a body produces motion Problem #3 (5 points) Which of the following describes Newton's I of Three Fundamental Law? a. The forces of action and reaction between bodies in contact have the same magnitude, same line of action, and opposite sense b. If the resultant force acting on a particle is not zero, the particle will have an acceleration proportional to the magnitude of the resultant and in the direction of this resultant force If the resultant force acting on a particle is zero, the particle will remain at rest (if originally at rest) or will move with constant speed in a straight line (if originally in motion) The action of one body on another tends to change the shape or state of motion (or both) of c. d. the other body

Explanation / Answer

Problem 2: equilibrium is defined when net force on body is zero. Hence correct andwer is "c"

Problem 3: Newtons first law states that in absense of a force a body will keep on moving with its original initial celocity or will remain at rest if it was initially at rest. Correc answer is hence "c".
