A downgrade of 5.0% meets an upgrade of 4.0%. This curve passes through the lowest point at 20 metres to the right of the intersection point

1. Find the length of the curve.

2. The reduced level at chainage 2450m, which is located on the downgrade, is 214.5m on the gradeline. The reduced level of the curve at the lowest point is 210m. Find the chainage at the lowest point.

3. Find the chainages and reduced levels of the two tangent points.

A 0.408 kg pendulum bob passes through the lowest part of its path at a speed of 2.71 m/s. What is the tension in the pendulum cable at this point if the pendulum is 86.8 cm long? A.) When the pendulum reaches its highest point, what angle does the cable make with the vertical? B.) What is the tension in the pendulum cable when the pendulum reaches its highest point?

Which of the labeled points is the point that the axis of rotation passes through?

There are two reasonable approximations to consider for the pencil in this problem: a cylinder and a thin rod. However, in this problem, we will treat the pencil as a uniform thin rod of length 15.0 cm and mass 10.0 g. The pencil rotates about an axis perpendicular to the plane of the figure. Which of the labeled points is the point that the axis of rotation passes through?

An electric current passes through a metal strip 0.50 cm by 5.0 cm by 0.10 mm, heating it at a rate of 128 W. The strip has emissivity e=1 and its surroundings are at 306 K. What will be the strip’s temperature(K) if it’s enclosed in an insulating box with thermal R=12 K/W resistance that blocks all radiation?

If quantity equals 10,000 units at the lowest point on the ATC curve and MC equals MR at 12,000 units then the monopoly firm will typically choose to produce where per unit cost of production is at the minimum. True or False When regulating a monopoly, a problem with setting price equal to average cost is a deadweight loss exists because output is not at its socially optimal level in this market and there is no incentive for the monopolist...
