Hanging Objects - Study Guides

Links to Practice Problems are at the BOTTOM of this Page

MY VIDEO Introduction to Hanging Object Problems is HERE

The basis for hanging object problems is the same for ALL of our forces problems:

  • If an object experiences unbalanced forces in the "x" or "horizontal" direction, it will accelerate in the direction of the unbalanced force.

  • If an object experiences unbalanced forces in the "y" or " vertical" direction, it will accelerate in the direction of the unbalanced force.

  • If an object is at rest in the "x" or "horizontal" direction the forces in that direction MUST be balanced or absent.

  • If an object is at rest in the "y" or "vertical" direction the forces in that direction MUST be balanced or absent.

Mathematically we express those situations as:

∑Fx = max

∑Fy= may

 

THEREFORE--

Our job is to

(1) determine if the forces acting in the horizontal ("x") direction are balanced or unbalanced

(2) determine if the forces acting in the vertical ("y") direction are balanced or unbalanced

HANGING PROBLEMS

MY Video Introduction to Hanging Problems is HERE

For one of OUR worked examples of a basic hanger problem go HERE.

For a basic hanger practice problem try #14 & 16 on the Physics Classroom HERE (Hint: it is easier to visualize those problems as 2 dimensional hanging problems with half of the ropes/cables pulling up to the left and the other half pulling up to the right).

A somewhat more difficult (but still very do-able) hanger problem is HERE

For a video/worked example, take a look at this (skip to 3:55)

A rather big-league (and kinda NASTY) hanger problem is HERE:
