Client comments on the Mechanical Analysis

The mechanical analysis provides useful information for the weight support in the lamp linkage. My few comments are:

• Please indicate the current weight of lamp head assembly. Therefore a design safety factor can be calculated.
• The analyze assumes a right angle between two lamp arms so that the lamp head assembly does not result any torque at joint 2. However, in most scenarios, the angle at joint 1 is less than 90 degrees (e.g. 60 or 45 degrees). An analysis for a worst-case scenario causing a maximum torque at joint 2 is required, and it would change the design safety factor mentioned in the first comment.
