- 1. A team was sent to the scene to complete the data collection needed for you to determine the coefficient of friction. To do this, the data collector drags a 13.265kg tire across the pavement. The force meter shows a force of 100N is needed to drag the tire at constant velocity. We also know that the coefficient of friction for the truck's tires is only 70% of the value for the car's tires.

If diameter of the cylinder increases, the pressure of the cylinder given from pump would be less. Select one: O True O False

Situation 4. Glycerine having a volume of 0.452m³ weighs 5,587 Newtons. a. What is the unit weight of glycerine in KN/m³? b. What is the density of glycerine in kg/m³? c. What is the specific gravity of glycerine?

The pipe assembly of the figure is supported by a fixed support at point A. A couple-moment and a force are applied at points B and C, respectively. In Cartesian coordinates, the applied couple-moment is MB = -150 k N-m, and the applied force is Fc = + 200ĵ Newtons. You may neglect the weight of the pipe assembly. 1. Draw a FBD which is suitable for solution of this problem, when seeking the unknown force and moment reactions at the fixed support, Point A. You may use the existing drawing given below. Your FBD must clearly/correctly show the force and moment reaction vectors. Use double arrowheads to distinguish moment vectors from force vectors. 2. Calculate F°MA, which is the moment generated at A due to the force applied at Point C. 3. Write the equations of equilibrium and solve to find the reactions at Point A. Specifically, find the force-reaction vector, A and the moment-reaction vector, *MA-

Choose correct answer: If the specific gravity of a liquid is 7, then its density is 7000 kg/mm3 Select one: True False

Q3: Explane in which case Fa has a maximum Value & minimum Value in Puling the car shown in Fig

convert (3.75 mm.kg)/(3ft).

if a hydraulic system has a cylinder containing fluid trapped between two pistons with equal diameters, how much force would the output (second) piston create if 25 joules of pressure were applied to the input (first) piston?
