You are required to synthesize and analyze a transporting mechanism. The purpose of the mechanism is to lift a box from ground and place it at the required position, as shown in Figure 1 by point B. The dimensions of box are 0.3 X 0.3 X 0.3 m³. The mechanism should take power from crank. The velocity of the box should be in the range of 20 - 25 m/min. You may assume the values of other parameters, if required.

I have the answers to the problems, but after calculating it, how do I determine what percentage of risky asset and risk-free asset for all three questions? Expected return of 15% and a standard deviation of 20% (use a risk-free rate of 0.06). 1. (4 mins) What percentage should an investor invest in the Optimal Risky portfolio and the risk-free asset if they have a risk aversion score of 2 and no borrowing is possible? A) 22% risky asset & 78% risk-free asset B) 87% risky asset & 13% risk-free asset C) 100% risky asset & 0% risk-free asset D) 112% risky asset & -12% risk-free asset E) 125% risky asset & -25% risk-free asset Y = (0.15 - 0.06) / (2 * 0.2^2) = 1.125 This means 100% in risky asset and 0% in risk-free asset. 2. What percentage should an investor invest in the Optimal Risky portfolio and the risk-free asset if they have a risk aversion score of 2 and borrowing is possible at the risk-free rate? A) 22% risky asset & 78% risk-free asset B) 87% risky asset & 13% risk-free asset C) 100% risky asset & 0% risk-free asset D) 112% risky asset & -12% risk-free asset E) 125% risky asset & -25% risk-free asset Same calculation, so 112.5% in risky asset and -12.5% in risk-free asset. 3. (4 mins) What percentage should an investor invest in the Optimal Risky portfolio and the risk-free asset if they have a risk aversion score of 2 and borrowing is possible at only an 8% borrowing rate? A) 22% risky asset & 78% risk-free asset B) 87% risky asset & 13% risk-free asset C) 100% risky asset & 0% risk-free asset D) 112% risky asset & -12% risk-free asset E) 125% risky asset & -25% risk-free asset Y = E - Borrowing Rate Y = (0.15 - 0.08) / (2 * 0.2^2) = 0.875
