PROBLEM 15.67 Robert's linkage is named after Richard Robert (1789-1864) and can be used to draw a close approximation to a straight line by locating a pen at Point F. The distance AB is the same as BF, DF and DE. Knowing that the angular velocity of plate BDF is 2 rad/s counterclockwise when 0= 90°, determine (a) the angular velocities of bars AB and DE, (b) the velocity of Point F. When = 90°, determine (a) the angular velocity of bar DE (b) the velocity of Point F.

F, = 50 N F2 = = 40 N -5 45° F1 = 20 N

Please turn this into 3d drawing, measurements are not important.

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

Please help. I need help with all 4 questions. Apply geometric tolerancing to part according to the instructions below. This exercise will provide you with experience in correctly applying and interpreting geometric tolerancing symbology. If you have trouble applying the symbols, page through this unit looking for similar examples. The Hole Bar in this unit is a good reference. Draw symbols and feature control frames clearly and neatly. 1. Establish all necessary basic dimensions. 2. Position the .250 hole within a diameter of .005 RFS relative to datum features A,B,C. 3. Position the three holes within a diamter of .012 at MMC relative to datum features A,B,C. 4. In the front view, identify the upper right corner as point "Y" and the lower left corner as point "X". Apply a profile tolerance of .020 between points X and Y relative to datum features A,B,C. Please refer to the attached image.

Select the correct statement regarding the solid model shown below. pattern1 It is easiest to create the 18 holes in this model by sketching each individual hole and using the extruded boss/base feature. It is easiest to create the 18 holes in this model by sketching one individual hole
