Across
  1. 4. are forces whose lines of actions intersect on a common point when they act on an object.
  2. 5. a condition in which two or more forces acting on an object reduces no acceleration because they balance each other out.
  3. 6. it is measured by the product of the force and the perpendicular distance from the axis of rotation to the line of action of the force.
  4. 7. mechanical advantage of a machine is the ratio of the distance Xa moved by the applied force to the distance Xl.
  5. 8. mechanical advantage of a machine is a ratio between the load force.
Down
  1. 1. are forces having their lives of action lie on a same plane.
  2. 2. the point of an object about which all gravitational torques cancel.
  3. 3. a force that tend to produce rotation in the axis.
  4. 4. the point at which all the mass of an object or system may be considered to be concentrated.
