ǀ
Expert Solution & Answer
To determine
Whether the statement, “A design problem in general is the characterization of a societal need” is true or false.
Explanation of Solution
Design process is a sequence of stages with a design model and a combination of methods, which are tools and techniques usable at different stages of design process.
Design process starts with the identification of needs of the society which is the primary input to a design problem. A design problem states the need of the society for which possible solutions are framed and evaluated.
Thus the statement, “A design problem in general is the characterization of a societal need” is true

Q1: The arms of a Porter governor are 250 mm long. The upper arms are pivoted on
the axis of revolution, but the lower arms are attached to a sleeve at a distance of 50
mm from the axis of rotation. The weight on the sleeve is 600 N and the weight of
each ball is 80 N. Determine the equilibrium speed when the radius of rotation of the
balls is 150 mm. If the friction is equivalent to a load of 25 N at the sleeve, determine
the range of speed for this position.
Q2: In a loaded Proell governor shown in Figure below each ball weighs 3 kg and
the central sleeve weighs 25 kg. The arms are of 200 mm length and pivoted about
axis displaced from the central axis of rotation by 38.5 mm, y=238 mm, x=303.5
mm, CE 85 mm, MD 142.5 mm. Determine the equilibrium speed.
