Concept explainers
Propose a force standard different from the example of a stretched spring discussed in the text. Your standard must be capable of producing the sane force repeatedly.

To propose: a standard force that is different from the example of a stretched spring.
Explanation of Solution
Introduction:
The force acting on a stretched string can be calculated by calculating the stretch produced in the string. Here, we need to propose a force standard which is different than this stretched spring.
The above figure shows the arrangement of Pascal’s law. When a force is applied on the beaker A, the water level of beaker B rises by a height h .
The pressure acting on the Beaker is given as
So,
V is the volume of liquid raised in the beaker B. So by using this standard, we can measure the forces acting on beaker A.

- Part A: kg (a) Water at 20 °C (p = 998.3 and v = 1 × 10-6 m²/s) flows through a galvanised m³ iron pipe (k = 0.15 mm) with a diameter of 25 mm, entering the room at point A and discharging at point C from the fully opened gate valve B at a volumetric flow rate of 0.003 m³/s. Determine the required pressure at A, considering all the losses that occur in the system described in Figure Q1. Loss coefficients for pipe fittings have been provided in Table 1. [25 marks] (b) Due to corrosion within the pipe, the average flow velocity at C is observed to be V2 m/s after 10 years of operation whilst the pressure at A remains the same as determined in (a). Determine the average annual rate of growth of k within the pipe. [15 marks] 4₁ Figure Q1.

You propose to bounce laser light off a mirror that is 53.5 km due east and have it detected by a light sensor that is 119 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west.(b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light.arrow_forwardA mirror hangs 1.67 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.41 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall.
