Question

A typical jamb-type tilting garage door opening mechanism is illustrated below: (Fitmaster Tilt-A-Dor^TM. http://www.world-business.net/australia/Tilt.htm accessed. Point G is the centre of mass, and point H is the fixing point for the garage door oper angle between AC and horizontal, omega is the corresponding angular speed. In this assignment you are required to write a report concerning the planar above. In your report, you must: Describe the links and pairs and calculate the mobility. Draw a fully dimensioned drawing of the mechanism shown, making reason; all dimensions necessary to define the location of all points A to G. Estimate the mass of the door. You may assume that other mechanism com massless. Plot the locus of all points from "door closed" to "door open".

Explanation / Answer

The locus point from the door closed to the door open

For the line AC, we have that the locus would be a circle centered in the point C with a radius of 1.5".

For the line BDE, we have that are two locus. One for the segment BD and another for the segment DE, for BD we have a circle centered in the point D with a radius of 1.25" and for DE we have a circle centered in the point D with a radius of 0.55"

For the line EF, we have that the locus would be a circle centered in the point F with a radius of 2".
