## An elevator performance

The following post has two questions namely;

## 1.An elevator performance

maximize an elevator performance using a motor that generates peak power at a rotational speed of 340
radians/second and a torque of 0.021 N-m. You spool of line has a radius of 0.03 rn.
The design (objective) function is given as
X = W2r3a

1. Calculate the maximum weight that can be lifted for each gear ratio
2. Calculate the time it would take to move the elevator one meter for each gear ratio
3. Calculate your design function’s value for each gear ratio
4. Plot the design function for all viable gear ratios as a function of gear ratio
5. Select the optimal gear ratio for your system to maximize the design function

## 2.Supporting teaching and learning in schools

.1. explain different types of bullying and the potential effects on children and young people. 1.2. outline the policies and procedures that should be followed in responses to concerns or evidence
of bullying and explain the reasons why they are in place. 1.3. explain how to support a child or young person and or their families when bullying is suspected or alleged. 2. understand how to work
with children and young people to support their safety and wellbeing. 2.1. explain how to support children and young people’s self-confidence and self-esteem. 2.2 Analyse the importance of
supporting resilience in children and young people. 2.3 explain why it is important to work with the child or young person to ensure they have strategies to protect themselves and make decisions
about safety. 2.4 explain ways of empowering children and young people to make positive and informed choices that support their wellbeing and safety 3. understand the importance of e-safety for
children and young people. 3.1. explain the risks and possible consequences for children and young people of being online and of using a mobile phone. 3.2. describe ways of reducing risk to
children and young people from: a. social networking b. internet use c. buying online d. using a mobile phone. 4. understand the importance of ensuring children and young people’s safety and
protection in the work setting. 4.1 explain why it is impotant to ensure children and young people are protected from harm within the work setting. 4.2. explain policies and procedures (in Great
Britain) that are in place to protect children and young people and adults who work with them. 4.3. evaluate ways in which concerns of poor practice can be reported whilst ensuring that whistle-
blowers and those whose practice or behavior is being questioned are protected. 4.4. explain how practitioners can take steps to protect themselves within their everyday practice in the work
setting and on offsite. visits.
