• September 1963 – The Corps of Engineers asked for a thorough analysis of the wind-load factors on the

Beneficial comments (recommendations, additions, A torque produces an angular acceleration or change in angular velocity. 2. Max. When you buy standard parts, they tend to be in customary units (i.e. Historical Timeline • March 1963 – Fabrication began on the crawler transporters in Ohio. If we go down for a 10-32 UNF screw, the assembly torque is 22.2 inch pounds.

MSFC-STD-486B, STANDARD, THREADED FASTENERS, TORQUE LIMITS FOR (NOV 1992)., This standard sets the acceptable torque values for threaded fasteners used in space vehicles and support equipment, the methodology for establishing the torque limits for the same, ad criteria for torque indicating devices on such fasteners. NASA/SP-8024, SPACECRAFT GRAVITATIONAL TORQUES, NASA SPACE VEHICLE DESIGN CRITERIA (GUIDANCE AND CONTROL) (MAY 1969)., Addresses gravitational torque effects and analysis for satellite design.

The distance used in the calculation of the torque is then the distance from the center of gravity perpendicular to the applied force.

TIGHTENING TORQUE FOR STAINLESS STEEL SCREWS Please use in heated-up condition the half of the values shown! This military standard is approved for use by all Departments and Agencies of the Department of Defense.

I could go up to 34.2 inch pounds but I have stripped so many fasteners I don’t risk it. 6–32 machine screws). • April 1963 – NASA decided to separate the launcher from its transporter and build only two crawlers. 1. If an object is not pinned, it rotates about its center of gravity when acted upon by an external force.

I’m a huge fan of Loctite so I go with that and the assembly spec. At JPL, everything is metric for the most part, although we do use fasteners with customary units (i.e. 1.

I’d use that lacking any other detailed information.
