When calculating the angular velocity of the Earth as it completes a full rotation on its own axis (a solar day), this equation is represented as: Ï avg = 2Ïrad/1day (86400 seconds), which works out to a moderate angular velocity of 7.2921159 Ã 10 -5 radians/second.
Roof sarking is a membrane that is fitted during tile or metal roof construction. The flexible membrane is usually installed under the battens to provide thermal insulation and to prevent water and dust penetration in the roof space.In bushfire prone areas flying embers cannot enter this space through the roof due to sarking protection.he flexible membrane is usually installed under the battens to provide thermal insulation and to prevent water and dust penetration in the roof space.

Stringhalt or springhalt is an involuntary, greater-than-normal flexion of the hock while the horse is in motion and may affect one or both hind limbs.tringhalt is apparently not painful and does not cause lameness in the usual sense.Some horses show a very mild hyperflexion of the hock during walking, while others jerk the leg up so violently that it strikes the abdomen and then pounds to the ground. Some horses show signs at each step, others only occasionally.
