I recently graduated Summa Cum Laude in Biomedical Engineering from Trine University this May. I am mostly interested in biomechanics and how the body can be related to a mechanical system. I greatly enjoyed all the engineering courses I took and earned an A in the following: Calculus 1/2/3, Differential Equations, Statics, Dynamics, Thermodynamics, Engineering Materials, Solid Mechanics, BME Instrumentation and Measurements 1/2, Biomechanics, Biofluids, Transport, Physics 1/2, Machine Component Design, Biomaterials, more core classes. I will be attending Marquette University this fall for a PhD in Biomedical Engineering focusing on trauma biomechanics. I would love the opportunity to solve engineering/physics/math/physiology problems for students. I am a very determined problem solver and I am excellent at composing captivating videos. I really like this idea to help students and I am looking forward to hearing from Numerade!
A variable force of 5$x^{-2}$ pounds moves an object along a straight line when it is $x$ feet from the origin. Calculate the work done in moving the object from $x=1$ ft to $x=10 \mathrm{ft.}$
When a particle is located a distance $x$ meters from the origin, a force of $\cos (\pi x / 3)$ newtons acts on it. How much work is done in moving the particle from $x=1$ to $x=2 ?$ Interpret your answer by considering the work done from $x=1$ to $x=1.5$ and from $x=1.5$ to $x=2.$
Shown is the graph of a force function (in newtons) that increases to its maximum value and then remains constant. How much work is done by the force in moving an object a distance of 8 $\mathrm{m} ?$
A force of 10 $\mathrm{lb}$ is required to hold a spring stretched 4 in. beyond its natural length. How much work is done in stretching it from its natural length to 6 in. beyond its natural length?
A spring has a natural length of 20 $\mathrm{cm} .$ If a $25-\mathrm{N}$ force is required to keep it stretched to a length of $30 \mathrm{cm},$ how much work is required to stretch it from 20 $\mathrm{cm}$ to 25 $\mathrm{cm} ?$
Suppose that 2 $\mathrm{J}$ of work is needed to stretch a spring from its natural length of 30 $\mathrm{cm}$ to a length of 42 $\mathrm{cm} .$(a) How much work is needed to stretch the spring from 35 $\mathrm{cm}$ to 40 $\mathrm{cm}?$(b) How far beyond its natural length will a force of 30 $\mathrm{N}$ keep the spring stretched?
