Need the following question answered, the subject is Mathematical Methods 2 (Mechanical Engineering). This is a University style question/practice paper with sections and I want the solutions to it, this comes with a formula sheet and if possible, use the formula sheet to answer the question. Need Calculations shown to each part of the question, My Teacher hasn't got back to me regarding the solutions so here I am, Thank you. Note: Please answer the question in UK style format as I don't think I'm allowed to go about the question in an American style. Thank you.

Bass-killer, a special plastic bait, is available at the Winona Fishing Cabin(WFC) at $10 per bag. The demand can be approximated by a normal distribution with a mean of 21 bags per week and a standard deviation of 3.4 bags per week. Lead time is 3 weeks, and there will be shipping cost $50 for each order. The new manager desires a chance of stockout of 5% or lower, and estimates the annual inventory holding cost is 20% of sales...
You are the operations manager of a firm that uses the continuous inventory control system. Suppose the firm operates 50 weeks a year, 350 days, and has the following characteristics for its primary item: • Demand 543 units/week • Price paid to supplier = $156/unit • Ordering cost = $77/order • Holding cost = $14/unit/year • Lead time = 2 weeks • Standard deviation in weekly demand = 38 units To achieve a service level of 99%, the safety stock...

Please explain and show all steps IV Standard Normal Distribution Table (Probability Content from -oo to z) The entries in this table give the cumulative area under the standard normal curve to the left ofz with...
Q5 The equation of the motion of the mechanical system shown in the following figure is governed by the following differential equation d2 x dx m7+9+= -f(t) - 3kx dt2 dt where m, C and k are mass, damping coefficient and spring constant, respectively. Consider the system with m = 10 kg, c = 80 Ns/m, k = 50 N/m, and the system is at rest at time t = 0 s. f(t) is the external force acting on the...
Model for Evaluation The model used for evaluation is the single degree of freedom lumped mass model defined by second order differential equation with constant coefficients. This model is shown in Figure 1. x(t)m m f(t) Figure 1 - Single Degree of Freedom Model The equation of motion describing this system can easily be shown to be md-x + cdx + kx = f(t) dt dt where m is the mass, c is the damping and k is the stiffness...

For lightly damped harmonic oscillators the displacement is given by x(t) = (A^(-bt/2m))*cos(ωt + φ) with period T = 2π / (sqrt((k/m)-(b^2/(4m^2)))). A) Show that this equation of motion obeys the force equation for a damped oscillator: F = −kx − bv. B) Shock absorbers in a pickup truck are designed to have a significant amount of damping. The effective spring constant of the four shock absorbers in a 1600 kg truck have an effective spring constant of 157,000 N/m....
