The photo shows a car jack that I accurately modeled in SolidWorks from measurements taken with a caliper and ruler. The renderings demonstrate that the lever arm assembly was functional enough to rotate up and down with the actuation of the hydraulic piston, while keeping the jack point plate level with the ground. The engineering drawing shows the most complex part of the assemby, the lever arm fulcrum. I am also CSWA certified with a 225/240 score (CSWA Certification Number: C-VR562CQF3A)
