Collar P slides outward at a constant relative speed along rod AB, which rotates counterclockwise with a constant angular velocity of 3.65 rad/s. Knowing r = 14.34 in when theta = 0, and the collar reaches B when theta = 98 degrees, determine the magnitude of the acceleration of the collar P just as it reaches B in ft/s^2.

a= 23.65 ft/s²

Explanation:

given

r= 14.34m

ω=3.65rad/s

Ф=Ф₀ + ωt

t = Ф - Ф₀/ω

= (98-0)×/3.65

98°= 1.71042 rad

1.7104/3.65

t= 0.47 s

r₁(not given)

assuming r₁ =20 in

r₁ = r₀ + ut(uniform motion)

u = r₁ - r₀/t

r₀ = 14.34 in= 1.195 ft

r₁ = 20 in = 1.67 ft

= (1.667 - 1.195)/0.47

0.472/0.47

u= 1.00ft/s

acceleration at collar p

a=rω²

= 1.67 × 3.65²

a = 22.25ft/s²

acceleration of collar p related to the rod = 0

coriolis acceleration = 2ωu

= 2× 3.65×1 = 7.3 ft/s²

acceleration of collar p

= 22.5j + 0 + 7.3i

√(22.5² + 7.3²)

the magnitude of the acceleration of the collar P just as it reaches B in ft/s²

a= 23.65 ft/s²

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

c) power lifting, will be your answer.
