The beauty of a bicycle wheel design is that the spokes (narrow cylindrical wires connecting the wheel center to the perimeter) are loaded in tension, despite the compressive force exerted via the bicyclist's weight. Consider a stainless steel spoke with a diameter of 2 mm, under a 1000 N (224 lbf) load. (aThe beauty of a bicycle wheel design is that the spokes (narrow cylindrical wires connecting the wheel center to the perimeter) are loaded in tension, despite the compressive force exerted via the bicyclist's weight. Consider a stainless steel spoke with a diameter of 2 mm, under a ) What is the (tensile) stress on the spoke?
What is the elastic strain in the spoke, given that approximation of the stainless steel as a linear elastic continuum is a reasonable approximation? If the spoke is initially 25.50 cm long, what is the spoke length under the maximum applied load?
steam is generated in a boiler. if the initial water enters the boiler as saturated water at 1000 psi a h542.4 btuibm
using bernoulli equation solves this question. a pipe of 300 m long has a slope of 1100 and converts from a 1.0 m
Ideally this is a brief title describing the main project theme. e.g. Design of a Domestic Security System. Name and Programme of Study Clearly identify your name, the programme of study. Aims of the Project Between 3 and 6 aims (more does n..
a wind turbine with a 90m-diameter rotor is rotating at 30 rpm under steady winds at an average velocity of 25 kmh.
A piston-cylinder device initially contains 0.007m^3 of nitrogen gas at 130kPa and 120C. The nitrogen gas is now expanded polytropically to a state of 100 kPa and 100C. Determine the boundary work done during this process. I know I need to use the fo..
a rectangular solar thermal collector sits on the roof of a house only one side is exposed to air and solar radiation
Two charged particles are initially separated by a distance d and the magnitude of the electric force on one is F1. If the distance is doubled, and the magnitude of the force on one of the particles is now F2, what is the ratio of F2/F1?
a rigid tank is connected by a valve to a supply line where refrigerant at 1.4 mpa and 100 degrees celsius flows
Given a lifting (rotating) cylinder in cross flow of radius a with a lift coefficient of C1=5, calculate the peak (suction) pressure coefficient, Cp. Use potential flow relations and assume 2-D.
One half of a mole of air is taken through the following processes in a closed piston-cylinder arrangement. From the initial state (V1 = 10 L, p1 = 1 atm) the gas is expanded at constant pressure to a volume of 20 L. It is then heated at constant vol..
a shaft of radius r and length l is subjected to a uniformly distributed shear. the shaft is fixed at one end and not
