Calculating the Amount of Work Done by Forces
The angle does not affect the amount of work done on the roller coaster car. 4. Ben Travlun carries a 200-N suitcase up three flights of stairs (a height of 10.0 m) and then pushes it with a horizontal force of 50.0 N at a constant speed of 0.5 m/s for a horizontal distance of 35.0 meters.
Types of Bearings: How They Work? Parts, Uses [PDF]
The axis of the shaft may vertical or horizontal. If the axis of the shaft is vertical, the thrust bearing is known as footstep bearing. If the axis of the shaft is horizontal, the thrust bearing is known as a roller bearing. #3 Foot Step Bearing. The figure shows a simple type of footstep bearing. It is suitable for supporting a vertical shaft.
STRESS AND DEFORMATION ANALYSIS - Pearson
90 PART onE Principles of Design and Stress Analysis The total force, RA, can be computed from the Pythagorean theorem, RA = 3RAx 2 + R Ay 2 = 3(40.0)2 + (26.67)2 = 48.07 kN This force acts along the strut AC, at an angle of 33.7° above the horizontal, and it is the force that tends to shear the pin in joint A. The force at C on the strut AC is also 48.07 kN acting upward to the

Types of Truss Structures | SkyCiv Engineering
The vertical members are in compression, whilst the diagonal members are in tension. This simplifies and produces a more efficient design since the steel in the diagonal members (in tension) can be reduced. This has a few effects – it reduces the cost of the structure due to more efficient members, reduces the self-weight, and eases the ...
