The unit represents a planar central force system in which multiple forces act on a single point of application. The compression jib and the tension tie make up the jib crane, which is attached by adjustable clamping elements to a retaining bar. It consists of a bar of adjustable length (compression jib) and a chain (tension tie), which is adjustable, and both incorporate a spring balance to measure the bar forces in them.
The Unit for studying Forces in a Jib Crane is designed to study the tensile and compressive forces in a planar central force system based on the example of a jib crane.
Based on the example of a jib crane, forces are determined experimentally, theoretically and graphically: resultant cable force, tensile force and compressive force. The magnitudes and directions of the forces are graphically determined with a force parallelogram.
A weight holder and a set of weights apply loads to the jib crane through the junction of the compression jib and the tension tie.
The unit consists of three members, three node discs and a set of weights with a weight holder. Each member is formed by a longitudinally bar, a spring and a dial gauge. These bars can form numerous simple bar structures with different angles. The bar forces occurring during the exercises are measured by the deformation of the springs situated in the middle of the bar with the dial gauges.
The Unit for studying Forces in a Simple Bar Structure represents a simple bar structure that allows the measurement of bar forces and the comparison of the experimental results with the calculations and the graphical method.
The set of weights and a weight holder are used to apply external load in the upper disc of the simple bar structure.
The method of joints and the calculations are used to determine the bar forces in the different bar structure to compare with the experimental results.
The members are joined by three node discs such that the joints can move freely. Snap-locks allow to engage the bars in the discs. Two of the discs also form the support of the simple bar structure, it can move freely and is fixed to the section base of the unit.

Anodized aluminum frame.

The floating motor is free to rotate and with a moment arm, rests against a load cell. Attached to the motor shaft is a coupling. The engineering drawing for the coupling mating half is supplied for the customer to produce.
Universal Drive Module Apparatus consists of a sturdy cradle, with bearings at either end. The motor is speed controlled using the control box supplied. The signal from the load cell is also fed directly into the control box. The torque being applied to the attached apparatus can be calculated using these parameters. The front panel of the control box has the speed control potentiometer, tachometer display for motor speed and the force display for the load cell signal. Suspended between the bearings is a motor, which gives drive to a variety of customer designed apparatus.
Experimental Capabilities:
Calculations involving torque, moment, speed and power
Introduction to drive system.
A precision-machined base plate holds the motor and its sensors. The Universal Dynamometer directly drives the Fluid Power machines. This means that the user has no need to fit or adjust the tension of belts and pulleys. The coupling between the Universal Dynamometer and all Fluid Power machines is a jaw-type coupling with a rubber element. The base plate has location points to give accurate and repeatable alignment onto each Fluid Power module.
The front of the motor drive and display unit has motor stop, start and speed controls. Outlets on the back of the unit give power for instruments supplied with the Fluid Power modules. The motor drive and display unit contains a variable-speed a.c. inverter drive and includes signal conditioning. It digitally displays speed, torque and shaft power. This reduces the need for multiple mains connections and gives a neater and safer equipment arrangement. The unit fits on the instrument frame fitted to all the Fluid Power modules.

The floor mounting frame can be easily converted to a bench-mounted version when using the bench mounting feet arrangement which is supplied as standard. The internal working dimensions for mounting experiments are 1.22m x 0.76m. Manufactured from high quality, ergonomic aluminium profile, the Universal Frame and Stand comprises an upper dual frame, which creates a continuous mounting slot around all four sides of the frame thus allowing the individual experiment components to be interchanged quickly. Should specimen beams longer than 1.22metres be used, the working gap allows the beams to run through the frame and protrude outside the working area.
