The rigid structure ABD is
supported at B by a 36-mm-diameter tie rod (1) and at A by a
29-mm-diameter pin used in a single shear connection. The tie rod
is connected at B and C by 24-mm-diameter pins used in double shear
connections. Tie rod (1) has a yield strength of 260 MPa, and each
of the pins has an ultimate shear strength of 320 MPa. A

A portion of a shaft where a gear is to be mounted has diameter of 50 mm. The gear transmits 335 N-m of torque. The shaft is to be made of SAE 1040 cold-drawn steel. The gear is made from SAE 8650 OQT 1000 steel The width of the hub of the gear mounted at this location is 45 mm. Design the key. The standard key dimension for a 50-mm-diameter shaft would be 14mm '9 mm Q-1 a rectangular. Material...
