Draw the loci of point B and point C for one oscillation of crank OA. Crank OA = 25 mm.

Question 1: LOCI (MECHANISM) Figure 1, which shows the schematic drawing of the mechanism, is not provided in the image. Without this figure, it is impossible to draw the mechanism and trace the loci of points B and C. The only given dimension is CRANK OA = 25 mm. To solve this problem, the following information from Figure 1 would be required: The initial position of crank OA. The length of the connecting rod BC. The position of the fixed swivel guide E relative to point O. The initial configuration of the mechanism. Once Figure 1 is available, the steps would involve: 1. Drawing the mechanism to scale 2:1: This means all given
