The figures below show a mechanism for a crushing machine with a kinematic diagram. The aim is to determine the number of li joints , half joints and DOF (Mobility) of the system, in addition, the drawing of the kinematic diagram must be checked. + 230 mm 230 mm 60 mm 25° Crank 180 mm 250 mm 320 mm Crushing ram 250 mm 180 mm 250 mm

Please show how to get answer

Which of the following statements below are incorrect? select all which apply.     A shear force diagram is a diagram of extermal force along the beam      a bending moment diagram is a diagram of internal bending moment along the beam caused by external loading     a bending moment diagram is a diagram of external moment along the beam     Shear force diagram could be considered as a function of beam load diagram as dV/dx = w, where V and w are internal shear force and external force density of the distributed force at one point along the beam, respectively.     Bending moment diagram could be considered as a function of shear force diagram as dM/dx = V, where M and V are internal bending moment and internal shear force at one cross-section along the beam, respectively.     A shear force diagram is a diagram of internal shear force along the beam caused by external loading

Question 2 and 3 please

Please Fill In the blanks where I have marked red X's using the questions and Image below. 1. On the drawing above, before any geometric controls are applied, what is the coaxility tolerance is implied between the diameters? 2. On the part above, apply datum feature symbols to create a datum axis A-B by using the right and left diamters. 3. Apply a position coaxility between the right and left diamter of 0.1 at MMC. 4. Apply a position tolerance to the large center diameter within a diameter of 0.3 in relation to the single datum axis established by both datum features A and B.

A,B,C please
