The spring-held follower ab has a weight of 0.83 lb and moves back and forth as its end rolls on the contoured surface of the cam, where r = 0.2 ft and latex: z=\left(0.1\sin2\theta\right) z = ( 0.1 sin ⁡ 2 θ ) ft. if the cam is rotating at a constant rate of 5 rad/s, determine the force at the end a of the follower when latex: \theta=45^\circ θ = 45 ∘ . in this position the spring is compressed 0.4 ft. neglect friction at the bearing c.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
