The designers of lamp mechanisms, such as that shown in the figure, usually rely on joint friction to aid in maintaining static equilibrium. For the present problem, assume that sufficient friction exists at point C to prevent rotation there, but ignore f
The designers of lamp mechanisms, such as that shown in the figure, usually rely on joint friction to aid in maintaining static equilibrium. For the present problem, assume that sufficient friction exists at point C to prevent rotation there, but ignore friction at all other joints. If the mass of the lamp fixture is 0.75 kg with mass center at G, determine the spring force Fs necessary for equilibrium in the position shown.

The rigid body shown below rotates around a fixed axis at O and position angle 0= 0 when the body is in static equilibrium. Force f(t) is applied to the body as shown below. The mass of the body is 12 kg and O is the center of mass. k=1000 N/m_for the spring. Mass moment of inertia I and damping constant c are to be determined. The plot below shows the response 0(t) when f(t) = 60 N is a...

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

A person holds two bricks together in one hand, pinching them as indicated by the arrows in the -figure to the left. As can be seen, the bricks have a tendency to swing apart at the bottom, contacting only at their top edges. We want to analyze the system to better understand its behavior and stability conditions (i.e. the bricks are not swinging around or falling out of the person's hand). This is done by analyzing a free body diagram...

SYNOPSIS The product manager for coffee development at Kraft Canada must decide whether to introduce the company's new line of single-serve coffee pods or to await results from the product's launch in the United States. Key strategic decisions include choosing the target market to focus on and determining the value proposition to emphasize. Important questions are also raised in regard to how the new product should be branded, the flavors to offer, whether Kraft should use traditional distribution channels or...
