Answer the two connected questions (Task A-1 and A-2). Provided in the last part are the guides and examples:
The process for large-scale manufacture of paper has been largely unchanged for the last 125 years. The pulp and paper industry today is highly capital intensive, and there is an ongoing drive towards process integration, thereby increasing the efficiency of utilization of available process resources. This paper deals with the Kraft process (see Fig. 1) though the general principles described can be extended to other pulping processes. As shown in Figure 1, five water sinks and four water sources are considered for in-plant water reuse/ recycle. Prior to water reuse/ recycle, the network requires a freshwater flow rate of 36,400 tonne/day and generates 37,186 tonne/day of wastewater (sum of the individual sink and source flow rates in Table 1). The freshwater source that is available for service has an impurity concentration (chloride content) of 4.2 ppm, which is higher than…

a.
What is the ideal mechanical advantage of this
system? The inclined plane dimensions are 7.2 meters
length and 1.8 meters height.
What effort force is required to move the 600N
create?
In practice, you need to supply an effort force
of 75 N to lift the crate. What is the efficiency?
C.
How could you redesign this compound
d.
machine so that the effort force needed was 50 N in
practice? Assume the efficiency is your response from
part C no matter what changes you make. Be specific
with the changes you propose (if you add pulleys state
how many, if you change the inclined plane
dimensions state the new dimensions, etc.).

Currently, you serve as a robotic engineer by a company, and your boss want you to design a robot in spatial space to satisfy the following conditions: i. Max reachable distance of the robot is 1 meter. ii. Only using revolute joints, connecting links and rigid load bearing links (the length of link is 0.5m). iii. The degree of freedom (Dof) of the robot is 2. What is your design, how many joints and links will you use? b. The payload of your design is 10 kg (each load bearing link can hold 5 kg, 5 kg+5 kg=10kg, the weight and payload of the connecting links will be ignored), but your boss wants your designed robots to handle 20 kg payload.
