The force that the bicep would generate when the distance of the fulcrum from the arm is 4 cm and the angle at which the arm must be held constant is 90°. Introduction: The contraction and relaxation of the muscle cells are responsible for the movement of a particular part of the body. The amount of pressure generated depends on the number of sarcomere units that slide over. Greater the force required, more will be the muscle fibers that slide over one another.

a.

Summary Introduction

To determine: The force that the bicep would generate when the distance of the fulcrum from the arm is 4 cm and the angle at which the arm must be held constant is 90°.

Introduction: The contraction and relaxation of the muscle cells are responsible for the movement of a particular part of the body. The amount of pressure generated depends on the number of sarcomere units that slide over. Greater the force required, more will be the muscle fibers that slide over one another.

Summary Introduction

To compare: The force needed when the point of insertion is 5 cm from the fulcrum to the force obtained when the distance of the fulcrum from the arm is 4 cm.

Introduction: The movement of the body is controlled by the contraction and relaxation of the skeletal muscles. A unit of muscle cells that undergoes contraction and relaxation is called sarcomere. The sarcomere is responsible for providing a striated appearance

b.

Summary Introduction

To determine: The force generated by the bicep when a band weighing 7kg is added on to the risk.

Introduction: Contraction in the muscle is important during weightlifting and the amount of force generated depends on the numbers of sarcomere units that slide over one another. Greater the force more will be the muscle fibers required that slide over one another.

Summary Introduction

To Compare: The force generated by the bicep when a band weighing 7kg is added on to the risk with the force if the object is placed 25cm away from the fulcrum.

Introduction: The force required to lift an object is directly proportional to the distance of the weight from the fulcrum and it is also dependent angle at which the weight has to be made stable.
